	A. Uchiyama Sokendai, Ibaraki, Japan K. Furukawa KEK, Ibaraki, Japan Y. Higurashi RIKEN Nishina Center, Wako, Japan
	Web technology is useful as a means to widely inform of accelerators and beam status.　For this purpose, WebOPI[1] as to web-based system using Ajax (Asynchronous JavaScript and XML) with EPICS was implemented by SNS. On the other hand, it is often necessary to perform the accelerator control from various locations as well as central control room during the beam operation and the maintenance.　However, it is not realistic to replace GUI-based operator interface (OPI) with Web-based system using Ajax technology because of interactive performance.　Therefore, as a next-generation OPI over the web using EPICS Channel Access (CA), we developed a client system based on WebSocket, which is a new protocol provided by Internet Engineering Task Force for Web-based system.　WebSocket is a web technology providing bi-directional, full-duplex communication channels over a single TCP connection.　By utlizing Node.js and WebSocket access library named Socket. IO, a WebSocket server was implemented. As a result, Web-based client systems became available not only in the central control room but also with various types of equipment for accelerator operation.

WECC03	Qt Based GUI System for EPICS Control Systems	EPICS, controls, synchrotron	10
	A. Rhyder, R.N. Fernandes, A. C. Starritt ASCo, Clayton, Victoria, Australia
	Funding: Australian Synchrotron The Qt based GUI system developed at the Australian Synchrotron for use on EPICS control systems has recently been enhanced to including support for imaging, plotting, user login, logging and configuration recipes. Plans are also being made to broaden its appeal within the wider EPICS community by expanding the range of development options and adding support for EPICS V4. Current development options include graphical and non graphical application development, 'code-rich' C++ development and simple 'code-free' GUI design. Additional development options will allow developers to manage the GUI framework's data needs themselves when required, as an alternative to letting the GUI objects manage their own data using the framework's Qt based EPICS data classes. Developers will be able to choose to manage the GUI data needs using the framework's Qt based EPICS data classes, or alternative data systems such as PSI's CAFE.

WEPD13	Serial Multiplexed Based Data Acquisition and Control System	controls, LabView, status, power-supply	29
	N.C. Patel, C.K. Chavda, K.G. Patel IPR, Bhat, Gandhinagar, India
	Data acquisition and control system consist of analog to digital converter, digital to analog converter, timer, counter, pulse generation, digital input / output etc depending upon requirement. All the components of the system must communicate with personal computer (PC) for data and control signal transmission using any one of the communication protocol like Serial, Parallel, USB, and GPIB etc. Serial communication is advantageous over other protocol like long distance data transmission, less number of physical connection, ease of implementation etc. The developed serial multiplexed system can control different module like ADC (for a small analog channel density, moderate sampling rate and local on-board memory) module, DAC (for controlling pressure valve, biasing voltage etc) module, DIO ( for system status monitoring and status control) module, Timer card ( for generating delayed pulse for triggering and synchronizing with other system) using single serial port. A LabVIEW based GUI program is developed for the individual communication of each module.

WEPD16	Development of Data Acquisition Software for VME Based System	HOM	35
	A. Kumar, A. Chatterjee, K. Mahata, K. Ramachandran BARC, Mumbai, India
	A Data Acquisition system for VME has been developed for use in accelerator based experiments. It is in use at BARC-TIFR laboratory. The development was motivated by the growing demand for higher throughput in view of the increasing size of experiments. The VME based data acquisition system provides a powerful alternative to CAMAC standards on account of higher readout speeds (100 ns/word) resulting in reduced dead time. Further, high density VME modules are capable of providing up to 640 channels in a single VME crate with 21 slots. The software system LAMPS[1], earlier developed for CAMAC based system and used extensively in our laboratory and elsewhere has been modified for the present VME based system. The system makes use of the VME library to implement Chain Block Transfer Readout (CBLT) and gives the option of both Polling and Interrupt mode to acquire data. Practical throughput of ~250 ns/word in zero-suppressed mode have been achieved. The developed software currently supports CAEN[2] V785 ADC, V775 TDC and V862 QDC and V830 Scalar Modules. The design, development and architecture of this DAQ system will be discussed. [1] http://www.tifr.res.in/~pell/lamps.html [2] http://caen.it/

WEPD19	Smart Structured Measurement Process for Versatile Synchrotron Beamline Data at ANKA	controls, synchrotron, vacuum, focusing	40
	T. Spangenberg, D. Haas, W. Mexner KIT, Karlsruhe, Germany
	An unstructured measurement process might deliver the needed quantity of primary data for an experiment. But the achievement of the scientific results depends more and more from the offered opportunities of embedding these measurement data into its specific context with a meta data description and a complete life cycle management. Obviously the design of a measurement process influences the potential applicability of an experimental setup for its scientific purpose and of course its options to fulfill a contemporary data management. ANKA's Tango based environment offers in principal varying approaches with different implementation efforts and coverage of scientific or information technology requirements. At ANKA we have set up a smart structured measurement process which stand out due to its seamless integration into the overall data management, the support of recent control concepts for fast data generation as well as its support of well time-tested SPEC based scan systems. The presented measurement process focuses to the minimal implementation for all involved components without a break of well accepted habits.

WEPD22	Post-Mortem Analysis of BPM-Interlock Triggered Beam Dumps at PETRA-III	controls, emittance, ion, synchrotron	43
	G.K. Sahoo, K. Balewski, A. Kling DESY, Hamburg, Germany
	PETRA-III is a 3rd generation synchrotron light source dedicated to users at 14 beam lines with 30 instruments. This operates with several filling modes such as 60, 240 and 320 bunches with 100mA or 40 bunches with 80mA at a positron beam energy of 6 GeV. The horizontal beam emittance is 1nmrad while a coupling of 1% amounts to a vertical emittance of 10pmrad. During a user run unscheduled beam dumps triggered by Machine Protection System may occur. In many cases the reason can be identified but in some it remains undetected. Though the beam is lost some signature is left in the ring buffers of the 226 BPM electronics where last 16384 turns just before the dump are available for post-mortem analysis. Scrutinizing turn by turn orbits and the frequency spectrum measured at a BPM can improve understanding of such a beam loss and may help to increase the efficiency of operation by eliminating the sources. Here we discuss in detail the functionality of a Java GUI used to investigate the reasons for unwanted dumps. In particular, the most effective corrector method is applied to identify correctors that might have perturbed the golden orbit leading to violations of the interlock limits.

WEPD25	Development of EPICS Channel Access Embedded ActiveX Components for GUI Development	controls, EPICS, monitoring, heavy-ion	54
	A. Roy, R.B. Bhole, S. Pal VECC, Kolkata, India
	The paper describes the integration of EPICS Channel Access protocol and Microsoft ActiveX technology towards developing a generalize operator interface (OPI) building facility for Windows platform. EPICS is used as the development architecture of the control system in Superconducting Cyclotron (SCC). Considering the operators' familiarity and compatibility with third party software, it was decided to use MS-Windows platform at operator interface level in SCC during commission. Microsoft Visual Basic (VB) is used on trial basis as OPI building platform to incorporate user specific features e.g. file system access for data storage and analysis, user authentication at OPI level etc. A set of EPICS Channel Access embedded ActiveX components is developed to ease the programming complexity and reduce developmental time of the OPI for Windows platform. OPIs, developed using these components and containing hundreds of process parameters, are being used reliably over a considerable period of time.

THIA03	The IUAC Tandem-LINAC Control System	controls, linac, monitoring, ion	94
	A. Kumar, B.K. Sahu, K. Singh IUAC, New Delhi, India
	The 16MV Tandem Van de Graff accelerator at IUAC is one of the earliest machines to go for a PC based control system. The PDP11, supplied with it, was replaced by an IBM PC running DOS before the accelerator was commissioned in 1989. The present system, commissioned in 1997 to include the LINAC, runs on a network of PCs under the GNU/Linux operating system. We have followed a distributed approach by grouping the signals, around 1000 in total, based on the location. Each group is connected to a server computer, by hardware interfaces like CAMAC, VME and custom hardware. The signals connected to each server PC are handled by a server program and they are accessible to the outside world, over a TCP/IP network, using a unique identifier consisting of a Label, Function and Unit. The features like a user interface, monitoring for alarm conditions, data logging and partial automation are handled by several client programs, communicating to multiple servers to access the hardware. The communication is done by passing a message packet and waiting for the reply. The message consists of the unique signal identifier and commands for setting/reading analog and digital parameter values. The development of the control system also resulted in low cost equipment for science education[1]. It also helped further development of the control system by additions like client programs in Python language. This feature enabled accelerator users to write simple scripts for tasks like setting the LINAC resonator parameters based on calculations, writing routines for partial automation etc. The system is cost effective, scalable and simple. It has shown very high reliability and ease of use during the past two decades of operation. [1] http://expeyes.inhttp://expeyes.in

	Data storage is a primary issue in any research facility. In the EPICS middleware based accelerator community, Channel Archiver has been always considered the main reference. It works with Oracle and MySQL, probably the best well known relational databases. However, demanding requirements at minimum costs have fostered the development of a wide range of alternatives, like protocol buffers (SLAC), MSDPlus (Consorzio RFX), SciDB (BNL) or Hypertable (IFNF). This document launches a tool called HyperArchiver, which was firstly developed at IFNF (Italy) and eventually customised by ESS Bilbao (Spain). Based on a NoSQL database named Hypertable, it focuses on large data sets management with maximum scalability, reliability and performance. Besides the update and further customization made at ESS Bilbao, HyperArchiver is presented with a set of GUIs, in order to provide an easy use and integration with any general control system. A LabVIEW VI and two cross-platform PyQt GUIs for both Hypertable data retrieval and HyperArchiver control have been developed and successfully tested at ESS Bilbao.

	The Tango[1] control system framework contains the communication bus with the standard communication modes as well as the basic hardware access modules, GUI tools and development kits, services and bindings to commercial products to set up a control system. Tango was developed by several synchrotron light sources that have to support not only the accelerator complex but also a lot of experimental end stations. For synchrotron experiments we have to control the whole process from basic hardware access over data taking to data analysis. This paper describes in the first part the special features of Tango allowing flexible experiment control. The dynamic configuration, the rapid hardware interface development and the sequencing and scanning framework are some examples. The second part gives an overview of some packages developed in the Tango community for experiment control: A HKL library for diffraction computation and diffractometer control, a library to control 2D detectors and a data analysis workbench with workflow engine for on-line and off-line data analysis. These packages are not part of Tango and can be used with other control systems. [1] http://www.tango-controls.org/

	RRCAT has commissioned a beam-line on Indus-2 synchrotron facility for carrying out Angle Dispersive X-ray Diffraction Measurement. A typical high pressure measurement is carried out by placing the sample in the Diamond Anvil Cell (DAC) with the sample located in a region of beam diameter within 50-100 μm. The X-Ray beam has to pass through the DAC to ensure maximum illumination of the sample with the X-Rays. An X-Y beam scanner/locater cum placement system is developed, which scans an area of 10 x 10 mm² with resolution of 10 to 100 μm in rough scan mode and fine scans selected area with programmable resolution of 2.5 to 25 μm. The scanner acts as slave to the PC in which master GUI grabs the data on serial port and plots the image of X-ray beam. It also analyzes and detects the coordinate with maximum intensity. Thus the DAC can be placed at the desired location with an accuracy of 2.5μm anywhere within 10 x 10 mm², for performing experiment. Developed system takes only ~5 minutes to search the beam and a few seconds to place DAC at any the desired location within the scanned area.

THCD05	A Flexible and Testable Software Architecture: Applying Presenter First to a Device Server for the DOOCS Accelerator Control System of the European XFEL	controls, PLC, undulator, laser	131
	A. Beckmann, S. Karabekyan, J. Pflüger XFEL. EU, Hamburg, Germany
	Presenter First (PF) uses a variant of Model View Presenter design pattern to add implementation flexibility and to improve testability of complex event-driven applications. It has been introduced in the context of GUI applications, but can easily be adapted to server applications. This paper describes how Presenter First methodology is used to develop a device server for the Programmable Logic Controls (PLC) of the European XFEL undulator systems, which are Windows PCs running PLC software from Beckhoff. The server implements a ZeroMQ message interface to the PLC allowing the DOOCS accelerator control system of the European XFEL to exchange data with the PLC by sending messages over the network. Our challenge is to develop a well-tested device server with a flexible architecture that allows integrating the server into other accelerator control systems like EPICS.

THPD04	Machine Throughput Improvement Achieved Using Innovative Control Technique	controls, PLC, linac, electron	144
	V. Sharma, S. Acharya, K.C. Mittal BARC, Mumbai, India
	Funding: BARC, Mumbai A 10MeV, Electron beam, RF Linac is operational at EBC, Kharghar, Navi Mumbai. The beam output scans one meter length in a scan horn. The product under irradiation is placed in a conveyor trolley where trolley is one meter long and one meter gap between the trolleys. With the constant speed of 5mtrs/min operation of trolley, the dose utilization is 50% since the beam falls in the gap between the trolleys. We have modulated the speed as 5mtrs./min when trolley gap is under the beam and 0.1 mtrs./min when trolley is under the beam. This way the beam utilization for the irradiation goes up to 98% hence 48% rise in productivity. A 20kV 10KJ Electromagnetic machining (EMM) facility is developed by APPD/BARC. In this EMM facility a large value capacitor is charged by a DC supply to a constant voltage. This charged capacitor is then discharged using triggered spark gap into a coil to generate intense magnetic field. This magnetic field generates the eddy current into the job piece to do the forming. We have used a PLC based control system to control the machine.

	⁹⁹Mo produced ^99mTc (t1/2=6hr, 140keV γ-ray) is the most useful radioisotope for nuclear diagnostics. High specific activity ⁹⁹Mo is supplied globally mainly by five old reactors whose routine or unscheduled maintenance shutdown causes supply irregularities that adversely affects patient management in nuclear medicine centres. ^99mTc may also be produced via ⁹⁸Mo(n,γ) in a natural MoO₃ target in reactor or by ¹⁰⁰Mo(n,2n)⁹⁹Mo or ¹⁰⁰Mo(p,2n)^99mTc reaction in cyclotron. To meet the crisis proposals are there to produce ⁹⁹Mo by ¹⁰⁰Mo(n,2n)⁹⁹Mo or ^99mTc directly by ¹⁰⁰Mo(p,2n)^99mTc in a cyclotron. Of the several separation methods of ^99mTc from molybdenum, the most common are adsorption column chromatography, sublimation and liquid-liquid solvent extraction. The conventional methods besides being cumbersome are often hazardous, polluting, require skilled manpower and facilities like fume hood and so are not always practically feasible for hospitals. To address these, VECC and BRIT, Kolkata have collaborated to develop an embedded system based automated ⁹⁹Mo/^99mTc generator from low specific activity ⁹⁹Mo using solvent extraction technique, supervised by a PC based GUI.

	D. Neidherr, D.H. Beck, H. Brand, F. Herfurth GSI, Darmstadt, Germany
	At the GSI accelerator complex in Darmstadt Germany the linear decelerator HITRAP is currently under commissioning. The aim is to provide highly charged ions up to bare uranium at cryogenic temperatures for various experiments as for instance tests of the theory of quantum electrodynamics. The ions are delivered with kinetic energies of about 4 MeV/u from GSIs experimental storage ring (ESR) and are slowed down in several steps until they are trapped and cooled down in a Penning trap. Whereas for the ESR as well as for the first sections of the linear decelerator the GSI accelerator control system is used the cooler trap as well as the subsequent transfer section to the experimental area are controlled with the LabVIEW based CS-framework developed at GSI. This framework is an object-oriented, event driven and multi-threaded framework with SCADA functionality, which is currently in use at many different experiments world-wide. For the HITRAP facility additional features like an online beam monitoring, realized with the integration of a LVOOP class capable of reading out IMAQ cameras, as well as a new GUI were implemented, which allows automatic scans of beam elements.

	Funding: ESS Bilbao Although EPICS is a mature software framework, the study and validation of new configurations of EPICS systems is very valuable, since new ideas open its evolution and improvement. So, the goal of the present work is to introduce new technologies under EPICS control structures and test different configurations with innovative hardware in this kind of applications. More specifically, it is intended to validate the use of non-stardard EPICS controllers. This paper presents a test bench using LabVIEW together with EPICS. LabVIEW eases and speeds up the development of control structures, avoids the hardware dependent developing costs and offers almost absolute compatibility with all kind of hardware used in control and data acquisition. To validate its use, it is mandatory to make a study facing this solution and EPICS standard methodology, specifically CODAC system used in ITER. To do so, a test bench is defined running both methods and its results compared. Following this scheme, the next step is to make a similar experiment introducing wireless links and replacing as many wires as possible.

	The analysis of most recent developments on high-performance software technologies suggests that new a design of distributed control systems (DCS) for particle accelerators may profit from solutions borrowed from cutting-edge Internet services. To fully profit from this new technologies the DCS model should be reconsidered, thus leading to the definition of a new paradigm. In this paper we present the conceptual design of a new control system for a particle accelerator and associated machine data acquisition system (DAQ), based on a synergic combination of a non-relational key/value database (KVDB) and network distributed object caching (DOC). The use of these technologies, to implement continuous data archiving and data distribution between components respectively, brought about the definition of a new control system concept offering a number of interesting features such as a high level of abstraction of services and components and their integration in a framework that can be seen as a comprehensive control services provider for GUI applications, front-end controllers, measurement and feedback procedures etc.

Web technology is useful as a means to widely inform of accelerators and beam status.　For this purpose, WebOPI[1] as to web-based system using Ajax (Asynchronous JavaScript and XML) with EPICS was implemented by SNS. On the other hand, it is often necessary to perform the accelerator control from various locations as well as central control room during the beam operation and the maintenance.　However, it is not realistic to replace GUI-based operator interface (OPI) with Web-based system using Ajax technology because of interactive performance.　Therefore, as a next-generation OPI over the web using EPICS Channel Access (CA), we developed a client system based on WebSocket, which is a new protocol provided by Internet Engineering Task Force for Web-based system.　WebSocket is a web technology providing bi-directional, full-duplex communication channels over a single TCP connection.　By utlizing Node.js and WebSocket access library named Socket. IO, a WebSocket server was implemented. As a result, Web-based client systems became available not only in the central control room but also with various types of equipment for accelerator operation.

Funding: Australian Synchrotron
The Qt based GUI system developed at the Australian Synchrotron for use on EPICS control systems has recently been enhanced to including support for imaging, plotting, user login, logging and configuration recipes. Plans are also being made to broaden its appeal within the wider EPICS community by expanding the range of development options and adding support for EPICS V4. Current development options include graphical and non graphical application development, 'code-rich' C++ development and simple 'code-free' GUI design. Additional development options will allow developers to manage the GUI framework's data needs themselves when required, as an alternative to letting the GUI objects manage their own data using the framework's Qt based EPICS data classes. Developers will be able to choose to manage the GUI data needs using the framework's Qt based EPICS data classes, or alternative data systems such as PSI's CAFE.

Data acquisition and control system consist of analog to digital converter, digital to analog converter, timer, counter, pulse generation, digital input / output etc depending upon requirement. All the components of the system must communicate with personal computer (PC) for data and control signal transmission using any one of the communication protocol like Serial, Parallel, USB, and GPIB etc. Serial communication is advantageous over other protocol like long distance data transmission, less number of physical connection, ease of implementation etc. The developed serial multiplexed system can control different module like ADC (for a small analog channel density, moderate sampling rate and local on-board memory) module, DAC (for controlling pressure valve, biasing voltage etc) module, DIO ( for system status monitoring and status control) module, Timer card ( for generating delayed pulse for triggering and synchronizing with other system) using single serial port. A LabVIEW based GUI program is developed for the individual communication of each module.

A. Kumar, A. Chatterjee, K. Mahata, K. Ramachandran
BARC, Mumbai, India

A Data Acquisition system for VME has been developed for use in accelerator based experiments. It is in use at BARC-TIFR laboratory. The development was motivated by the growing demand for higher throughput in view of the increasing size of experiments. The VME based data acquisition system provides a powerful alternative to CAMAC standards on account of higher readout speeds (100 ns/word) resulting in reduced dead time. Further, high density VME modules are capable of providing up to 640 channels in a single VME crate with 21 slots. The software system LAMPS[1], earlier developed for CAMAC based system and used extensively in our laboratory and elsewhere has been modified for the present VME based system. The system makes use of the VME library to implement Chain Block Transfer Readout (CBLT) and gives the option of both Polling and Interrupt mode to acquire data. Practical throughput of ~250 ns/word in zero-suppressed mode have been achieved. The developed software currently supports CAEN[2] V785 ADC, V775 TDC and V862 QDC and V830 Scalar Modules. The design, development and architecture of this DAQ system will be discussed.

An unstructured measurement process might deliver the needed quantity of primary data for an experiment. But the achievement of the scientific results depends more and more from the offered opportunities of embedding these measurement data into its specific context with a meta data description and a complete life cycle management. Obviously the design of a measurement process influences the potential applicability of an experimental setup for its scientific purpose and of course its options to fulfill a contemporary data management. ANKA's Tango based environment offers in principal varying approaches with different implementation efforts and coverage of scientific or information technology requirements. At ANKA we have set up a smart structured measurement process which stand out due to its seamless integration into the overall data management, the support of recent control concepts for fast data generation as well as its support of well time-tested SPEC based scan systems. The presented measurement process focuses to the minimal implementation for all involved components without a break of well accepted habits.

PETRA-III is a 3rd generation synchrotron light source dedicated to users at 14 beam lines with 30 instruments. This operates with several filling modes such as 60, 240 and 320 bunches with 100mA or 40 bunches with 80mA at a positron beam energy of 6 GeV. The horizontal beam emittance is 1nmrad while a coupling of 1% amounts to a vertical emittance of 10pmrad. During a user run unscheduled beam dumps triggered by Machine Protection System may occur. In many cases the reason can be identified but in some it remains undetected. Though the beam is lost some signature is left in the ring buffers of the 226 BPM electronics where last 16384 turns just before the dump are available for post-mortem analysis. Scrutinizing turn by turn orbits and the frequency spectrum measured at a BPM can improve understanding of such a beam loss and may help to increase the efficiency of operation by eliminating the sources. Here we discuss in detail the functionality of a Java GUI used to investigate the reasons for unwanted dumps. In particular, the most effective corrector method is applied to identify correctors that might have perturbed the golden orbit leading to violations of the interlock limits.

The paper describes the integration of EPICS Channel Access protocol and Microsoft ActiveX technology towards developing a generalize operator interface (OPI) building facility for Windows platform. EPICS is used as the development architecture of the control system in Superconducting Cyclotron (SCC). Considering the operators' familiarity and compatibility with third party software, it was decided to use MS-Windows platform at operator interface level in SCC during commission. Microsoft Visual Basic (VB) is used on trial basis as OPI building platform to incorporate user specific features e.g. file system access for data storage and analysis, user authentication at OPI level etc. A set of EPICS Channel Access embedded ActiveX components is developed to ease the programming complexity and reduce developmental time of the OPI for Windows platform. OPIs, developed using these components and containing hundreds of process parameters, are being used reliably over a considerable period of time.

The 16MV Tandem Van de Graff accelerator at IUAC is one of the earliest machines to go for a PC based control system. The PDP11, supplied with it, was replaced by an IBM PC running DOS before the accelerator was commissioned in 1989. The present system, commissioned in 1997 to include the LINAC, runs on a network of PCs under the GNU/Linux operating system. We have followed a distributed approach by grouping the signals, around 1000 in total, based on the location. Each group is connected to a server computer, by hardware interfaces like CAMAC, VME and custom hardware. The signals connected to each server PC are handled by a server program and they are accessible to the outside world, over a TCP/IP network, using a unique identifier consisting of a Label, Function and Unit. The features like a user interface, monitoring for alarm conditions, data logging and partial automation are handled by several client programs, communicating to multiple servers to access the hardware. The communication is done by passing a message packet and waiting for the reply. The message consists of the unique signal identifier and commands for setting/reading analog and digital parameter values. The development of the control system also resulted in low cost equipment for science education[1]. It also helped further development of the control system by additions like client programs in Python language. This feature enabled accelerator users to write simple scripts for tasks like setting the LINAC resonator parameters based on calculations, writing routines for partial automation etc. The system is cost effective, scalable and simple. It has shown very high reliability and ease of use during the past two decades of operation.

Data storage is a primary issue in any research facility. In the EPICS middleware based accelerator community, Channel Archiver has been always considered the main reference. It works with Oracle and MySQL, probably the best well known relational databases. However, demanding requirements at minimum costs have fostered the development of a wide range of alternatives, like protocol buffers (SLAC), MSDPlus (Consorzio RFX), SciDB (BNL) or Hypertable (IFNF). This document launches a tool called HyperArchiver, which was firstly developed at IFNF (Italy) and eventually customised by ESS Bilbao (Spain). Based on a NoSQL database named Hypertable, it focuses on large data sets management with maximum scalability, reliability and performance. Besides the update and further customization made at ESS Bilbao, HyperArchiver is presented with a set of GUIs, in order to provide an easy use and integration with any general control system. A LabVIEW VI and two cross-platform PyQt GUIs for both Hypertable data retrieval and HyperArchiver control have been developed and successfully tested at ESS Bilbao.

The Tango[1] control system framework contains the communication bus with the standard communication modes as well as the basic hardware access modules, GUI tools and development kits, services and bindings to commercial products to set up a control system. Tango was developed by several synchrotron light sources that have to support not only the accelerator complex but also a lot of experimental end stations. For synchrotron experiments we have to control the whole process from basic hardware access over data taking to data analysis. This paper describes in the first part the special features of Tango allowing flexible experiment control. The dynamic configuration, the rapid hardware interface development and the sequencing and scanning framework are some examples. The second part gives an overview of some packages developed in the Tango community for experiment control: A HKL library for diffraction computation and diffractometer control, a library to control 2D detectors and a data analysis workbench with workflow engine for on-line and off-line data analysis. These packages are not part of Tango and can be used with other control systems.

RRCAT has commissioned a beam-line on Indus-2 synchrotron facility for carrying out Angle Dispersive X-ray Diffraction Measurement. A typical high pressure measurement is carried out by placing the sample in the Diamond Anvil Cell (DAC) with the sample located in a region of beam diameter within 50-100 μm. The X-Ray beam has to pass through the DAC to ensure maximum illumination of the sample with the X-Rays. An X-Y beam scanner/locater cum placement system is developed, which scans an area of 10 x 10 mm² with resolution of 10 to 100 μm in rough scan mode and fine scans selected area with programmable resolution of 2.5 to 25 μm. The scanner acts as slave to the PC in which master GUI grabs the data on serial port and plots the image of X-ray beam. It also analyzes and detects the coordinate with maximum intensity. Thus the DAC can be placed at the desired location with an accuracy of 2.5μm anywhere within 10 x 10 mm², for performing experiment. Developed system takes only ~5 minutes to search the beam and a few seconds to place DAC at any the desired location within the scanned area.

Presenter First (PF) uses a variant of Model View Presenter design pattern to add implementation flexibility and to improve testability of complex event-driven applications. It has been introduced in the context of GUI applications, but can easily be adapted to server applications. This paper describes how Presenter First methodology is used to develop a device server for the Programmable Logic Controls (PLC) of the European XFEL undulator systems, which are Windows PCs running PLC software from Beckhoff. The server implements a ZeroMQ message interface to the PLC allowing the DOOCS accelerator control system of the European XFEL to exchange data with the PLC by sending messages over the network. Our challenge is to develop a well-tested device server with a flexible architecture that allows integrating the server into other accelerator control systems like EPICS.

A 10MeV, Electron beam, RF Linac is operational at EBC, Kharghar, Navi Mumbai. The beam output scans one meter length in a scan horn. The product under irradiation is placed in a conveyor trolley where trolley is one meter long and one meter gap between the trolleys. With the constant speed of 5mtrs/min operation of trolley, the dose utilization is 50% since the beam falls in the gap between the trolleys. We have modulated the speed as 5mtrs./min when trolley gap is under the beam and 0.1 mtrs./min when trolley is under the beam. This way the beam utilization for the irradiation goes up to 98% hence 48% rise in productivity. A 20kV 10KJ Electromagnetic machining (EMM) facility is developed by APPD/BARC. In this EMM facility a large value capacitor is charged by a DC supply to a constant voltage. This charged capacitor is then discharged using triggered spark gap into a coil to generate intense magnetic field. This magnetic field generates the eddy current into the job piece to do the forming. We have used a PLC based control system to control the machine.

⁹⁹Mo produced ^99mTc (t1/2=6hr, 140keV γ-ray) is the most useful radioisotope for nuclear diagnostics. High specific activity ⁹⁹Mo is supplied globally mainly by five old reactors whose routine or unscheduled maintenance shutdown causes supply irregularities that adversely affects patient management in nuclear medicine centres. ^99mTc may also be produced via ⁹⁸Mo(n,γ) in a natural MoO₃ target in reactor or by ¹⁰⁰Mo(n,2n)⁹⁹Mo or ¹⁰⁰Mo(p,2n)^99mTc reaction in cyclotron. To meet the crisis proposals are there to produce ⁹⁹Mo by ¹⁰⁰Mo(n,2n)⁹⁹Mo or ^99mTc directly by ¹⁰⁰Mo(p,2n)^99mTc in a cyclotron. Of the several separation methods of ^99mTc from molybdenum, the most common are adsorption column chromatography, sublimation and liquid-liquid solvent extraction. The conventional methods besides being cumbersome are often hazardous, polluting, require skilled manpower and facilities like fume hood and so are not always practically feasible for hospitals. To address these, VECC and BRIT, Kolkata have collaborated to develop an embedded system based automated ⁹⁹Mo/^99mTc generator from low specific activity ⁹⁹Mo using solvent extraction technique, supervised by a PC based GUI.

At the GSI accelerator complex in Darmstadt Germany the linear decelerator HITRAP is currently under commissioning. The aim is to provide highly charged ions up to bare uranium at cryogenic temperatures for various experiments as for instance tests of the theory of quantum electrodynamics. The ions are delivered with kinetic energies of about 4 MeV/u from GSIs experimental storage ring (ESR) and are slowed down in several steps until they are trapped and cooled down in a Penning trap. Whereas for the ESR as well as for the first sections of the linear decelerator the GSI accelerator control system is used the cooler trap as well as the subsequent transfer section to the experimental area are controlled with the LabVIEW based CS-framework developed at GSI. This framework is an object-oriented, event driven and multi-threaded framework with SCADA functionality, which is currently in use at many different experiments world-wide. For the HITRAP facility additional features like an online beam monitoring, realized with the integration of a LVOOP class capable of reading out IMAQ cameras, as well as a new GUI were implemented, which allows automatic scans of beam elements.

Although EPICS is a mature software framework, the study and validation of new configurations of EPICS systems is very valuable, since new ideas open its evolution and improvement. So, the goal of the present work is to introduce new technologies under EPICS control structures and test different configurations with innovative hardware in this kind of applications. More specifically, it is intended to validate the use of non-stardard EPICS controllers. This paper presents a test bench using LabVIEW together with EPICS. LabVIEW eases and speeds up the development of control structures, avoids the hardware dependent developing costs and offers almost absolute compatibility with all kind of hardware used in control and data acquisition. To validate its use, it is mandatory to make a study facing this solution and EPICS standard methodology, specifically CODAC system used in ITER. To do so, a test bench is defined running both methods and its results compared. Following this scheme, the next step is to make a similar experiment introducing wireless links and replacing as many wires as possible.

The Cryogenic Data Acquisition and Control system (CRYO-DACS) at IUAC was commissioned successfully in the year 2002 and has been continuously in operation since then with uptime better than 95%. The aim of CRYO-DACS is to control and acquire many analog and digital cryogenic parameters of super conducting LINAC and related equipments like beam-line cryostats, helium compressors, cryogenic distribution etc. The complete system is implemented using two VME crates, housing I/O modules, placed far apart and interconnected using Ethernet. The software implementation and maintenance have also been trouble-free which used IOWORKS as the development tool for embedded CPUs running VxWORKS. The OPC Client was developed using VB6 & MSACCESS RDBMS for data logging, viewing and trending under Windows 2000 stable server. In summary, this paper will elaborate the implementation, use and related failures faced for last 10 years and the subsequent corrective actions taken to keep the system running for such a long time round the clock along with some future plans.

Electron-positron collider VEPP-2000 has been commissioned at Budker Institute of Nuclear Physics. The first experiments on high energy physics has been started at the end of 2009. The paper presents architecture, implementation and functionality of hardware and software of the collider control system. The hardware of the system consists of high current main field power supplies, steering coils power supplies, pulse-elements, RF subsystems and some other special subsystems (such as vacuum, temperature, etc.). The system is based on modern industrial protocol CAN-bus and specialized electronic BINP manufactured blocks according the standard. The paper describes implementation of different subsystems based on CANbus devices, and operating characteristics and their possibilities. Other standards and protocols like CAMAC, VME and so on also used in the system. The software according to hardware system consists of interacting subsystems responding on different acceleration facility parts. Control system software is based on several TCP/IP connected PC platforms under operating system Linux and uses client-server techniques.

The analysis of most recent developments on high-performance software technologies suggests that new a design of distributed control systems (DCS) for particle accelerators may profit from solutions borrowed from cutting-edge Internet services. To fully profit from this new technologies the DCS model should be reconsidered, thus leading to the definition of a new paradigm. In this paper we present the conceptual design of a new control system for a particle accelerator and associated machine data acquisition system (DAQ), based on a synergic combination of a non-relational key/value database (KVDB) and network distributed object caching (DOC). The use of these technologies, to implement continuous data archiving and data distribution between components respectively, brought about the definition of a new control system concept offering a number of interesting features such as a high level of abstraction of services and components and their integration in a framework that can be seen as a comprehensive control services provider for GUI applications, front-end controllers, measurement and feedback procedures etc.
