MOZ02	The Concept of EMBL Beamline Control at Petra III	controls, feedback, brilliance, vacuum	22
	U. R. Ristau, M. DiCastro, S. Fiedler, A. Pazos EMBL, Hamburg P. Duval DESY, Hamburg
	The EMBL is located at the DESY site in Hamburg and operates 7 beam lines at the DORIS III synchrotron. Currently the EMBL Hamburg constructs three new beam lines at the new PETRA III synchrotron. In the past the level of beam line automation is significantly increased. Control system tasks are changed to more data through put, faster reaction times and require more flexibility. The control electronic has to allow fast feedbacks and precise data synchronization. Sample changer offer higher speed and sample capacity. The transport of videos and the huge amount of experimental data via the control system requires networks with large bandwidth and high efficient control system transport protocols. The EMBL has chosen TINE as beam line control system. TINE features like the multi cast option and the efficient TINE transport protocol help to minimize the network load. The control electronic will be the real time PLC control EtherCat for motor control and data acquisition. Fast data acquisition will be performed with FPGA and PXI electronic. Presented will be the beam line control concept, the control electronic layout and the first finished applications.

MOZ03	Beam Emittance Measurement Tool for CEBAF Operations	controls, emittance, quadrupole, electron	25
	P. Chevtsov, M. G. Tiefenback Jefferson Lab, Newport News, Virginia
	A new software tool was created at Jefferson Lab to measure the emittance of the CEBAF electron beams. The tool consists of device control and data analysis applications. The device control application handles the work of wire scanners and writes their measurement results as well as the information about accelerator settings during these measurements into wire scanner data files. The data analysis application reads these files and calculates the beam emittance on the basis of a wire scanner data processing model. Both applications are computer platform independent but are mostly used on LINUX PCs recently installed in the accelerator control room. The new tool significantly simplifies beam emittance measurement procedures for accelerator operations and contributes to a very high availability of the CEBAF machine for the nuclear physics program at Jefferson Lab.

TUX02	Experiences with PVSS II as an Overall SCADA System for ANKA	controls, storage-ring, radiation, diagnostics	46
	W. Mexner, K. Cerff, M. Hagelstein, T. Spangenberg FZK, Karlsruhe
	The control system of the synchrotron radiation source ANKA at Forschungszentrum Karlsruhe was segmented into several autonomous parts. The storage ring have been controlled by the ACS control system, the infrastructure facilities by the supervisory control and data acquisition system (SCADA) named IGSS, and several autonomous PLC based interlock systems for the accelerators and beam lines. Each system required special knowledge for maintenance and failure diagnostics. In order to improve the manageability and to reduce cost, the SCADA system PVSS II has been chosen as a supervisory control system, integrating each of the individual parts. As the interface is open and easy to handle the integration was straightforward. The majority of the existing control systems have been integrated with limited man power during a one year period followed by a continuous optimization process. The new system with a common look and feel for beam lines and machine was quickly accepted by beam line scientists, technicians and operators.

TUX03	Evolution and Status of the e-Logbooks at the ESRF	controls, power-supply, storage-ring, radio-frequency	49
	L. Hardy, J. M.C. Chaize, O. Goudard ESRF, Grenoble S. D. Cross, D. R. Fraser, N. V. Hurley St James Software, Cape Town
	In 2004 the ESRF moved to electronic logbooks. Such logbooks should be configurable enough to be used in several situations: document management, exchange of technical information and, in the Control Room, as a powerful tool for storing and retrieving information at a glance. The St James software company developed such a product which met our constraints and which is easy to configure. Moreover, this product can be tailored and evolved with time by its users and allows automatic access to control system parameters. After gaining experience with several logbooks using the old version 4 system, a new more user-friendly version which offers extensive customisation possibilities has been launched. This new version, J5, has already been interfaced to the ESRF control system (Tango) through a Python binding. This allows automatic triggering of records on specific events and the generation of automatic reports from the history database system. J5 can use an LDAP server for security management.

TUX04	j5 Logbook - A Commercial e-logbook	controls, beam-transport, synchrotron-radiation, vacuum	52
	D. G. Moore St James Software, Cape Town O. Goudard, L. Hardy ESRF, Grenoble
	j5's EventStream module provides an interface for exchanging data with services such as Tango and OPC. j5 models this data as a series of events. Each combines information on the source of the data, its reliability, when it was generated and whether it represents an alarm condition, with the actual data from the external device. Adding a new type of data source requires only the implementing of the very modest data device API. For Tango, the implementation built on PyTango while for OPC Windows COM was used. Data devices support both pulling values and subscription to event channels. Once in j5, events may flow through event pipes, being transformed and triggering actions such as the addition of logbook entries. In other cases, j5 may pull events from the data server, e.g. to populate data fields automatically when new log entries are created. A key feature enabled by EventStream is the ability to attach graphs of 1D and 2D arrays directly to logbook entries as they are added. This combines the event processing capabilities of j5 with its document attachment and thumbnail generation to make the information present in such arrays immediately available to logbook users.

TUP002	Performance Tests of Digital Signal Processing for GSI Synchrotron BPMs	pick-up, closed-orbit, acceleration, controls	79
	K. Lang, P. Forck, T. Hoffmann, P. Kowina, U. Rauch GSI, Darmstadt G. Janša Cosylab, Ljubljana
	The Beam Position Monitoring System at GSI heavy ion synchrotrons consists of twelve stations. Each of the four BPM plates is connected to a Libera Hadron unit from I-Tech Company for digitization and position calculation. The raw data of one BPM sampled by 125 MS/s with 14 Bit ADCs are reduced to about 20 MB/s by the onboard FPGA, resulting in a bunch-by-bunch position readout. In addition, different timing signals with various requirements are used to verify the functionality of the FPGA algorithms. For a closed orbit measurement, the data of all twelve Liberas have to be read in parallel. For communication, the Xilinx Rocket IOs is used, that allows up to 1GBit/s data output. Over a dedicated network, the data are merged for further usage on a high performance PC. We describe the general architecture and present first performance tests.

TUP014	Software Control for a Multilayer Monochromator	controls, synchrotron-radiation, radiation, monitoring	110
	A. Pazos, M. DiCastro, S. Fiedler, D. Fulla, T. Gehrmann, C. Hermes, D. Jahn, F. Ridoutt, U. R. Ristau, B. Robrahn EMBL, Hamburg
	The EMBL is located at the DESY site in Hamburg and operates 5 beamlines at the DORIS III storage ring. Currently the EMBL Hamburg is in charge to build three new beamlines at the new PETRA III high-brilliance synchrotron radiation source which will commence user operation in 2009. A new multilayer double-crystal monochromator has been developed in house. This has been a real application test for the software and hardware architecture of the new PETRAIII beamlines. An embedded-PC controls the electronic integrated in the EtherCAT real-time Ethernet bus. Inside this PC a logic of PLC’s directly drives the hardware allowing real time data acquisition. The control of the system is distributed and remotely accessible by a connection to a TINE device server. The commissioning phase has been done using a Labview TINE client application. The client is able to perform on-the-fly scans thanks to the PLC's base logic. In the following paper the different pieces of the system are presented as well as an overview of the instrument.

TUP022	A .NET Interface for Channel Access	controls, synchrotron-radiation, laser, radiation	134
	G. Cox STFC/DL, Daresbury, Warrington, Cheshire
	The control system for Accelerators and Lasers In Combined Experiments (ALICE) under construction at Daresbury Laboratory uses EPICS and vxWorks on VME64x. The client software in use during the commissioning of the accelerator is based on PC consoles running Red Hat Linux 9. Synoptic displays and engineering panels are created using the Extensible Display Manager (EDM) and other standard EPICS extension software is used for archival, alarm handling etc. A similar EPICS based control system is being used for the commissioning of the Muon Ionisation Cooling Experiment (MICE) under construction at Rutherford Appleton Laboratory. The Synchrotron Radiation Source (SRS) control system uses a bespoke control system with client software on PC consoles running Microsoft Windows. We would like to employ a similar approach for the operational client software on ALICE and MICE with Channel Access (CA) clients running on Microsoft Windows PC consoles. This paper presents the .NET Channel Access interface developed at Daresbury and showcases .NET client applications being developed for both ALICE and MICE operations.

WEX02	Remote Access to the Canadian Light Source	controls, monitoring, coupling, fibre-optics	143
	E. Matias, D. Chabot, D. G. Maxwell, D. Medrano CLS, Saskatoon, Saskatchewan C. H. Armstrong IBM, Markham, Ontario M. Fuller, S. McIntryre UWO, London, Ontario
	As part of a joint project CLS, the University of Western Ontario, IBM and BigBangwidth has developed a beamline remote access system that has been demonstrated on the CLS VESPERS and the alft x-ray source facilities. This system utilizes web-browsers as a thin client that can be connected to servers at the CLS over conventional Ethernet or User Configuration Light Paths. The RBA system is based on the concept of a Service Oriented Architecture and provides access control, data acquisition, data storage and based visualization. More recently the system has been modified to permit experimental data to be streamed into third party analysis tools such as Quartz Imaging X-one. This system is now being extended to form the basis for ScienceStudio and integrated experiment management system.

WEZ02	The Canadian Light Source Control System - A Case Study in the Use of Single Board Computers and Industrial PC Equipment for Synchrotron Control	controls, storage-ring, electron, booster	157
	E. Matias, D. Beauregard, R. Berg, D. Chabot, T. Wilson, G. Wright CLS, Saskatoon, Saskatchewan
	Since 2000 the Canadian Light Source (CLS) control system architecture has been based on to the use of small single board computers for equipment control running the RTEMS operating system. CLS has started to migrate to a new off-the-shelf single board computer platform (based on the Moxa embedded computer platform. In 2001 CLS also adopted the use of fibre optic bridges and industrial PC equipment in place of VME slot zero controllers. Today this continues to be the basis of our higher performance data acquisition and control applications. This paper outlines the lessons learned from nearly eight years of operational use of the this technology.

WEP005	Monolithic DAQ System for Beam Diagnostics at the HIT Medical Accelerator Facility	controls, diagnostics, ion, medical-accelerators	177
	M. Schwickert, T. Fleck, A. Reiter GSI, Darmstadt
	The Heidelberg Ion Therapy Center HIT is presently in the final phase of commissioning. HIT consists of a two-stage linac followed by a compact heavy-ion synchrotron. The ion beam can be delivered to two horizontal treatment places and a gantry structure for 360° patient treatment. In this contribution we report on the basic concepts for the integration of the beam diagnostic data acquisition into the overall accelerator control system and the distributed timing devices. The equipment-side abstraction layer of facility-wide device classes and its seamless integration besides device control units, e.g. for power supplies, is presented and first operational experiences of the machine commissioning are discussed. As examples for the data acquisition of the high-energy beam transport section the detection of beam profiles using MWPCs and Scintillation Screens is presented, as well as measurements of beam intensity using ionization chambers.

	M. DiCastro, S. Fiedler, A. Pazos, F. Ridoutt, U. R. Ristau EMBL, Hamburg
	The EMBL is located at the DESY site in Hamburg and operates 5 beamlines at the DORIS III sotorage ring. Currently the EMBL Hamburg is in charge to build three new beamlines at the new PETRA III high-brilliance synchrotron radiation source which will commence user operation in 2009. In this paper a reconfigurable FPGA based control solution is presented to monitor and analyze in real time beamline experiments. The hardware is suitable to acquire fast and high sensitive electronic signals, analyzing them for feedback closed loops. The system is included in the TINE control system and can be remotely controlled and configured. The control hardware consists of a National Instrument PXI crate equipped with a real time controller and R-series FPGA. The Labview real-time object oriented programming to control the system is presented as well as the adaptation of the hardware to various applications. The solution is shown starting from simulation and then testing on the existing DORIS test beamlines used for PETRA III.

WEP013	Integration of ALMA Common Software and National Instruments LabVIEW	controls, coupling, monitoring, synchrotron-radiation	195
	K. Žagar, A. Žagar Cosylab, Ljubljana B. Bauvir, G. Chiozzi, P. R.M. Duhoux ESO, Garching bei Muenchen
	Among the candidate technologies for the Extremely Large Telescope (E-ELT) are ALMA Common Software (ACS) and LabVIEW. ACS is a CORBA-based control system infrastructure that implements a container-component model. It allows developers to focus on development of components that define application logic, with ACS-provided containers addressing infrastructural issues of distributed control systems such as remote procedure calls, logging, configuration, etc. LabVIEW is a commercial solution provided by National Instruments which allows rapid construction of user interfaces and control loops. Control loops can execute on Windows and Linux operating systems, as well as real-time control systems and FPGA circuits. In this paper, we present an approach for integration of ACS and LabVIEW. We accessed ACS from a LabVIEW user interface (both sending of data into ACS, and receiving data from ACS). Also, we accessed a real-time LabVIEW process (parts of which were executing in FPGA) from ACS – again in both directions. From the LabVIEW perspective, the approach is platform-independent as it is based on a Simple TCP/IP Messaging protocol.

THX02	Photon Beamline Control System as a Product	controls, photon, site	221
	M. Kobal, P. Medvešček, G. Pajor, R. Šabjan, I. Verstovšek Cosylab, Ljubljana
	Every beamline is different, which makes it impossible to buy a control system of the shelf. Nevertheless well tested and customizable building blocks can be prepared, which are then put together according to customer requirements. Delivering a fully operational control system is not just software development, but also gathering specifications, writing documentation, testing the hardware and trimming the software on site. Based on the delivery of a number of working beamlines, this paper will prove that we have optimized all stages and can guarantee that the purchased control system will be delivered on time, will work according to specifications and will be properly documented. The customers can also count on support.

THX03	TCP/IP Vulnerabilities of Embedded-System Implementations	controls, storage-ring, monitoring, linac	224
	T. Sugimoto, M. Ishii, T. Masuda, T. Ohata, T. Sakamoto, R. T. Tanaka JASRI/SPring-8, Hyogo-ken
	TCP/IP is established as a de facto standard network-communication protocol. Development of the TCP/IP enables us to build a large-scale distributed control system. Recent accelerator-control system consists of many TCP/IP devices; not only computers, but also embedded devices such as digital multimeters, oscilloscopes, multi-channel analyzers, and so on. Since these embedded devices are designed with limited hardware resources, most devices use subset of the TCP/IP components. The limited resources and components therefore cause many problems such as vulnerabilities of TCP/IP implementations. In SPring–8, by increasing the number of network-connected instruments with latent vulnerabilities, more trouble have arisen such as packet flooding and unexpected response delaying. One of the most serious trouble is hang-up of pulse-motor controllers* based on embedded operating system. To determine cause of the trouble, network-connected instruments were inspected using basic TCP/IP tools and security scanners. As a result, we successfully found vulnerabilities of embedded implementation. In this presentation, the cause of vulnerabilities in embedded systems will be discussed. * T.
