  EPICS is a set of Open Source software tools, libraries, and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for scientific instruments such as particle accelerators, telescopes, and other large scientific experiments. An IOC (Input/Output Controller) is a network node that controls and/or monitors a collection of devices. An IOC contains a memory resident real-time database. The real-time database has a set of "smart" records. Each record is an instance on a record of a particular type. JavaIOC is a JAVA implementation of an EPICS IOC. It has many similarities to a Version 3 EPICS IOC, but extends the data types to support structures and arrays.

  Since the first JET pulse in 1983, the raw data collected per ~40s of plasma discharge (pulse) has roughly followed a Moore's Law-like doubling every 2 years. Today we collect up to ~10GB per pulse, and the total data collected over ~70,000 pulses amounts to ~35TB. Enhancements to JET should result in ~60GB per pulse being collected by 2010. An ongoing challenge is to maintain the pulse repetition rate, data access times, and data security. The mass data store provides storage, archiving, and also the data access methods. JET, like most fusion experiments, provides an MDSplus (http://www.mdsplus.org) access layer on top of its own client-server access. Although ITER will also be a pulsed experiment, the discharge will be ~300-5000s in duration. Data storage and analysis must hence be performed exclusively in real time. The ITER conceptual design proposes a continuous timeline for access to all project data. The JET mass data store will be described together with the planned upgrades required to cater for the increases in data at the end of 2009. The functional requirements for the ITER mass storage system will be described based on the current status of the ITER conceptual design.

TOPA03 The IRMIS Universal Component-Type Model controls, insertion, factory, site 82
 
  • D. Dohan
    ANL, Argonne, Illinois
  The IRMIS toolkit provides a relational description of the accelerator/facility hardware and how it is assembled. To create this relational model, the APS site infrastructure was successively partitioned until a set of familiar, "unit-replaceable" components was reached. These items were grouped into a set of component types, each characterized by the type's function, form factor, etc. No accelerator "role" was assigned to the components, resulting in a universal set of component types applicable to any laboratory or facility. This paper discusses the development of the universal component-type model. Extension of the component types to include port definitions and signal-handling capabilities will be discussed. This signal-handling aspect provides the primary mechanism for relating control system software to accelerator hardware. The schema is being extended to include references to the device support for EPICS-supported component types. This suggests a new approach to EPICS database configuration in which the user, after selecting a particular hardware component, is provided with links to the support software to be used in building the EPICS application.

TPPA22 Standard Device Control via PVSS Object Libraries in ALICE controls, radiation, monitoring, heavy-ion 135

  The device control in the LHC experiments is based on OPC servers and PVSS SCADA systems. A software framework enables the user to set up his PVSS project for the different devices used. To achieve a homogeneous operational environment for the ALICE experiment, these devices need to be controlled thought standard interfaces. PVSS panels act as the upper control layer and should allow for full control of the devices. The PVSS object-oriented feature has allowed the development of device Object Libraries. The Object Libraries have two main advantages. On one hand, they ease the operator task thanks to the introduced standardization of the various device control panels. On the other hand, they reduce the developer’s job as only basic software knowledge is required to set up a control application for a standard device. This paper will describe the device control architecture including PVSS, software framework, and OPC server. It will describe the Object Libraries developed for some devices, and it will explain how the Object Libraries integrate tools in the ALICE controls environment, such as Finite State Machines, access control, and trending.

  Shanghai Synchrotron Radiation Facility is a third-generation light source with 150MeV LINAC, 3.5Gev booster, and storage ring. The SSRF control system is a hierarchical standard accelerator control system based on EPICS. The VME 64X system and PLCs are used for various low-level device controls and interlock systems. Serial device servers connect serial devices and instrumentation to the Ethernet. All control subsystems are under construction. The hardware and software system development environment has been set up. Most of the subsystem models, such as the digital power supply control and event timing systems, have been set up and are being tested with devices on schedule. The high-level physical application environment has been set up and undergone online testing of device control using MatLab with Accelerator Toolbox and a middle layer. A set of tools (e.g., configuration tools and an alarm handler) has been set up for the center's database. An enhanced distributed archive engine has been created to store data using native XML data type with XML schema for data storage. Various testing results of the control systems for SSRF equipment will be described in this paper.  
 
TPPB09 The ALICE Transition Radiation Detector Control System controls, radiation, collider, monitoring 181
 
  • J. M. Mercado
    Heidelberg University, Physics Institute, Heidelberg
  The ALICE experiment at the LHC incorporates a transition radiation detector (TRD) designed to provide electron identification in the central barrel at momenta in excess of 2 GeV/c as well as fast (6 us) triggering capability for high transverse momentum (pt > 3 GeV/c) processes. It consists of 540 gas detectors and about 1.2 million electronics readout channels that are digitized during the 2 us drift time by the front-end electronics (FEEs) designed in full custom for on-detector operation. The TRD detector control system (DCS) back end is fully implemented as a detector-oriented hierarchy of objects behaving as finite state machines (FSMs). PVSS II is used as the SCADA system. The front-end part is composed of a 3-layer software architecture with a distributed information management (DIM) server running on an embedded Linux on-detector system pool (about 550 servers) and the so-called InterComLayer interfacing the DIM client in PVSS as well as the configuration database. The DCS also monitors and controls several hundreds of low- and high-voltage channels, among many other parameters. The layout of the system and status on installation and commissioning are presented.  
 
TPPB10 Target Diagnostic Instrument-Based Controls Framework for the National Ignition Facility (NIF) diagnostics, controls, target, laser 184

    LLNL, Livermore
  The extreme physics of targets shocked by NIF’s 192-beam laser are observed by a diverse suite of diagnostics including optical backscatter, time-integrated and gated X-ray sensors, and laser velocity interferometry. Diagnostics for fusion ignition are being planned. Many diagnostics are developed at other sites, but ad hoc controls could prove costly or unreliable. The instrument-based controls (IBC) framework facilitates development and eases integration. Each diagnostic typically uses an ensemble of electronic instruments attached to sensors, digitizers, and other devices. Each individual instrument is interfaced to a low-cost WindowsXP processor and Java application. Instruments are aggregated as needed in the supervisory system to form the integrated diagnostic. Java framework software provides data management, control services, and operator GUIs. IBCs are reusable by replication and configured for specific diagnostics in XML. Advantages include small application codes, easy testing, and better reliability. Collaborators save costs by reusing IBCs. This talk discusses target diagnostic instrumentation used on NIF and presents the IBC architecture and framework.

  The control system of the RIKEN RI-Beam Factory (RIBF) is based on the Experimental Physics and Industrial Control System (EPICS). To control magnet power supplies of cyclotrons and their beam transport lines, we are using VME and CAMAC as I/O Controllers (IOCs) depending on a kind of their interface boards. To control beam-diagnostic equipment and vacuum systems, small single-board computers mounted with Linux are used as IOCs. Other devices of cyclotrons like RF are controlled by PCs, which are independent systems from EPICS. These details will be reported. Furthermore, we will report about the RIBF beam interlock system using Melsec PLCs. We started beam commissioning of RIBF in July 2006 and succeeded in extracting uranium beam from the Superconducting Ring Cyclotron (SRC), which is the last of the multi-stage accelerators of the RIBF, on March 23, 2007.

  The successful achievement of many physics goals of the CMS experiment required the design of an electromagnetic calorimeter (ECAL) with an excellent energy and angular resolution. The choice of the scintillating crystals, photodetectors, and front-end readout electronics of the ECAL has been made according to these criteria. However, certain characteristics of the chosen components imposed challenging constraints on the design of the ECAL, such as the need for rigorous temperature and high voltage stability. For this reason an ECAL Detector Control System (DCS) had to be carefully designed. In this presentation we describe the main DCS design objectives, the detailed specifications, and the final layout of the system. Emphasis is put on the system implementation and its specifc hardware and software solutions. The latest results from final system prototype tests in the 2006 ECAL test-beam program, as well as the system installation and commissioning at the CMS experimental construction site, are also discussed.

  The China Spallation Neutron Source (CSNS) is an accelerator-based high-power project currently under planning in China. For the similarities between the CSNS and the U. S. Spallation Neutron Source (SNS), the SNS control framework will be used as a model for the machine controls. And the software framework used at SNS, XAL, is a natural choice for the CSNS. This paper provides a controls overview and progress. Also, the technical plan, schedule, and personnel plan are discussed.

  The Jülich Centre for Neutron Science (JCNS) is constructing a new “best-of-class” Neutron Spin Echo Spectrometer (NSE) at the Spallation Neutron Source (SNS) in Oak Ridge. Using superconducting precession coils, energy resolutions of 0.7 neV can be achieved with the new instrument, which will start commissioning in autumn 2008. Recently, JCNS constructed an NSE at its branch lab at the FRM-II reactor in Garching. This so-called JNSE is in its commissioning phase now, and its control and data acquisition system is based on the “Jülich-Munich Standard.” The “Jülich-Munich Standard” includes the TACO control system developed by the ESRF and the extensive use of industrial-type front-end equipment, e.g., PLCs, fieldbus systems (PROFIBUS DP), or remote I/Os. Since there are a lot of components and structures that are common for both instruments, the same technology shall be used for the SNS-NSE, of course. On the other hand, local SNS standards have to be supported since the SNS-NSE shall fit into the DAQ-infrastructure of the SNS, e.g., regarding data formats, interface to the timing system, or the ability to include local sample environments.

  We describe the control system for the new Frascati injector project (SPARC). The injector starts operation in fall 2007, and at that time the control system must be fully operative and integrate all tools to help the machine operation. To allow a fast development of the control system, we made some choices: (1) Labview as developing system due to its diffusion in the Frascati labs and being a standard-de-facto in the acquisition software; (2) GigaBit Ethernet as interconnection bus in order to have sufficient bandwidth for data exchange; and (3) PCs as front-end CPUs and operator console because they have enough computing power. In 2006 a first operation of the control system, during the SPARC gun test performed with the e-meter diagnostic apparatus, allowed us to test the architecture of the control system both from the hardware and software points of view. All control applications for magnetic elements, vacuum equipment, RF cavities, and some diagnostics have been developed and debugged online. An automatic process stores in a database operating information both periodically and on data change. Information can be sent automatically or manually to our e-logbook.  
 
TPPB29 The OPC-Based System at SNS: An EPICS Supplement monitoring, SNS, controls, site 223
 
  • R. J. Wood, M. P. Martinez
    ORNL, Oak Ridge, Tennessee
  The Power Monitoring System at the Spallation Neutron Source (SNS) is a Windows-based system using OLE for Process Control (OPC) technology. It is employed as the primary vehicle to monitor the entire SNS Electrical Distribution System. This OPC-based system gathers real-time data, via the system's OPC server, directly from the electrical devices: substations, generators, and Uninterruptible Power Supply (UPS) units. Thereupon, the OPC-EPICS softIOC interface reads and sends the data from the OPC server to EPICS, the primary control system of SNS. This interface provides a scheme for real-time power data to be shared by both systems. Unfortunately, it engenders obscure anomalies that include data inaccuracy and update inconsistency in EPICS. Nevertheless, the OPC system supplements the EPICS system with user-friendly applications—besides the ability to compare real-time and archived data between the two systems—that enable performance monitoring and analysis with ease. The OPC-based system at SNS is a complimentary system to EPICS.

  The PSI 590-MeV Cyclotron is already more than 30 years in operation. However, it still holds the world record in continuous beam power. There is an active experiment program being pursued, and new experiments are planned and being built. In addition, the beam intensity is being upgraded by 50%. The control system has been through several incremental upgrades. However, the new requirements and other developments at PSI (other accelerator facilities) force again an upgrade. This time the whole architecture of the system is to be changed. The controls hardware architecture will be changed and the underlying software will move to EPICS. All this has to happen without compromising the operation schedule. In the upgrade program we are planning to benefit from several new developments, both in-house and together with the community. The central technologies to be used will be presented. The issue of how to tackle the somewhat contradictory goals of upgrading on the fly will be discussed.

    BARC, Mumbai
  The SSW system developed by Fermilab, USA, has been the main device heavily used since 2004 at CERN for certain required measurements of all the LHC Quadrupole assemblies as well as certain measurements for the LHC Dipoles. All these structures also include various small and large corrector magnets. A novel system is proposed, based on three years of operational experience in testing the LHC Magnets on a round-the-clock basis. A single stretched wire system is based on the wire cutting the magnetic flux, producing the electrical potential signal. Presently this signal is integrated with a VME-based data acquisition system and is used to analyse the magnetic field. The acquisition and control is currently done via a SUN workstation communicating between different devices with different buses and using different protocols. The new system would use a PXI based data acquisition system with an embedded controller; the different devices are replaced by PXI-based data acquisition and control cards using a single bus protocol and on one chassis. The use of windows based application software would enhance the user friendliness, with overall costs of the order of 10 KCHF.

  Baseline design of the Taiwan photon Source (TPS) control system of NSRRC is proposed. The control system design is based on EPICS toolkits due to it has large user base in synchrotron light source around the world. Guidelines for hardware platform and operating system choice will be addressed. The standard hardware interface driver is developing and testing now. The asynchronous driver of EPICS will be applied to be the most of standard hardware interface. The expected control system for TPS will provide versatile environments for machine commissioning, operation, and research. The open architecture led machine upgrade or modify without toil. Fewer efforts for machine maintenance are essential. Performance and reliability of the control system will be guarantee form the design phase. Design consideration will be summary in this report.  
 
WPPA06 An Embedded EPICS Controller Based on Ethernet/Serial Box controls, target, vacuum, ion 328
 
  • L. R. Shen, G. Y. Jiang
    SSRF, Shanghai
  The control system of SSRF takes the Ethernet as backbone. All kinds of serial devices such as vacuum pumps are connected to Linux IOCs via a kind of Ethernet/serial box made by Moxa company. In the preresearch stage of SSRF, the old model of this Ethernet/serial box was only a simple Ethernet/serial protocol converter which was functioned by firmware. Aim to this, we have developed several kinds of EPICS device drivers based on NetDev for our serial devices. Recently, Moxa company has upgraded the converter by replacing old arm9 CPU with a more powerful Intel Xscale CPU. It supports Monta Vista Linux as its embedded OS, also cross-compiler is provided to make further development available. Since we have decided to use the new model of converter in our facility finally, we manage to port EPICS IOC core on Monta Vista Linux and implement the same function on the new converter as old one's to avoid modifying existent EPICS device driver. By these, the dedicated Linux IOC can be omitted and the whole system can be more efficient and expandable. Details of the necessary integration work and initial operation experience will be discussed in this paper.

  The MAMI electron accelerator cascade of three Racetrack Microtrons (RTMs) has been upgraded by a 4th stage, a Harmonic Double Sided Microtron (HDSM), raising the output energy from 0.855GeV to 1.5GeV. The control system for this worldwide unique machine has been built by extending and updating the well proven system of the three RTMs described at the ICALEPCS'99*. To accomplish this, software to control a couple of new devices had to be implemented, the operator interface was rebuilt and new PC-based VME-front-end computers were developed. To supply the large number of correction dipole steerers on the 43 recirculation paths, a new type of multi-channel power supplies was developed in-house. An enhanced system for digitising the signals of the rf-position monitors on the linac axes has been set up to improve the automatic beam position optimisation in the RTMs and to enable it in the HDSM.

WPPA09 Development of Embedded System for Running EPICS IOC by Using Linux and a Single Board Computer controls, target, vacuum, diagnostics 334

  We constructed a control system based on the Experimental Physics and Industrial Control System (EPICS) for the RIKEN RI-beam Factory (RIBF) project. Nowadays, the PC-based EPICS Input Output Controller (IOC) is used in many laboratories because it is available for use on the Linux x86 platform since EPICS was upgraded to version R3.14. If the number of PC-based IOC increases, the probability of trouble rises dramatically. Consequently, it is difficult to supply reliable hardware. Furthermore, if a lot of desktop PCs are used for running IOC only, it is very hard to maintain it. The purpose of this development is to give the high durability system for running IOC computer and the ability for all accelerator operators to maintain it easily. We expect we can solve the problems described above using a diskless and fanless embedded single board computer (SBC) for running IOC and managing IOC in the fileserver collectively. For this reason, we developed a compact and simple Linux distribution specialized for running IOC and introduced IOC, which is installed in the SBC, into RIBF control system. In our contribution, we report this system and present the status in detail.

  There are 70 vertical and 70 horizontal correctors for Pohang Light Source. Until 2003, power supplies for these correctors were based on 1980’s technology, so the global orbit feedback system was not possible with poor 12-bit resolution. In 2003, a task force team was assembled to develop new power supplies with BESSY type ADC cards. By Summer 2004, two vertical correctors in each lattice were connected with new power supplies, and the global orbit feedback was available within the accuracy of 5 microns. However, this replacement was not enough to satisfy the beam stability requirement of 2 microns for PLS. We have launched another power supply design based on all digital technology. This attempt was completed within a year, and 80 units were assembled in house. Currently, the global orbit feedback system is running successfully with new digital power supplies and the compensation of chamber motion due to the thermal load by using digital displacement transducers attached on each BPMs.

  We upgraded the BPM data acquisition system of the PLS 2.5-Gev storage ring with the use of RFM (Reflective Memory). Our present BPM data acquisition system is based on EPICS VME IOC. It uses an analog-to-digital converter with 16-bit resolution and a 100-KHz conversion rate to digitize BPM raw electric signals. To get better position data from the digitized raw BPM data, we developed BPM data-averaging software utilizing RFM. With this averaging software, we could average 4000 samples of raw BPM data with the refresh rate of 2 seconds and get much better position data compared with the previous one. We installed data-averaging software and reflective memory modules into 12 local BPM IOCs for the routine operation. We are also planning to develop a fast global feedback system using RFM to improve beam quality in the near future.

  We introduced the virtualization technology to more than 50 workstations in SPring-8 beamlines to reduce into 8 servers. The virtualization technology is a hot topic for server computing. It enables to consolidate a lot of computers to a few host computers. We presented the experiment of introduction of the virtualization technology at previous ICALEPCS conference. In SPring-8, about 50 beamlines are in operation. Each beamline had one workstation for an operator console to avoid interference from other beamline operation. The virtualization technology reduces hardware and maintenance costs while ensuring independency of a computing environment in each beamline. This paper describes the process and the result of the migration to the virtualization environment. In addition, we show changes of a topological network configuration for the virtualization environment.

  The Spallation Neutron Source Front End (FE) is comprised of a 35-70 mA volume H-source, a multi-element electrostatic LEBT including chopping and steering, a 402.5MHz RFQ with low output emittance, and a 2.5MeV MEBT that also includes chopping. The original control system was designed and built by LBNL during 2000-2002 and commissioned at SNS in 2003. The FE control system design occurred early in the project and preceded finalization of SNS control system standards. The system was implemented based on Allen-Bradley VMEBus Remote I/O Scanners and PLC5s with Flex I/O interfaced via Remote I/O communication. The FE control system is now being upgraded to comply with the SNS standard PLC implementation and to improve reliability and maintainability. Details on the upgrade will be presented in this paper.

  The CLIC Test Facility 3 (CTF3) is an R&D machine being built to validate concepts that will be used for the Compact Linear Collider (CLIC). Because CTF3 is an instrumentation-intensive machine, a considerable amount of money is put into the acquisition hardware and high-quality cables used to bring the instrument signals to the digitalization crates with as little degradation as possible. The main idea of this new approach is to reduce the distance between the signal source and the A/D conversion, reducing the cost of the cabling. To achieve that, we have developed a radiation hard front-end that we install directly into the accelerator tunnel. This front-end deals with the digitalization of the signals after an analog buffering. Afterwards, the data are sent to a computer through the SPECS field bus. Finally, the digitalized signals are made available to the operation crew thanks to a server implementing the OASIS (Open Analogue Signal Information System) interfaces in the CERN Front-End Software Architecture (FESA). After a presentation of this low-cost solution to BPM acquisition, the paper gives the results of the first integration tests performed in the CTF3 machine.

  The large number of gates in modern FPGAs including processor cores allows implementation of complex designs, including a core implementing Java byte-code as the instruction set. Instruments based on FPGA technology are composed only of digital parts and are totally configurable. Based on experience gained on our products (a delay generators producing sub-nanosecond signals and function generators producing arbitrary functions of length in the order of minutes) and on our research projects (a prototype hardware platform for real-time Java, where Java runtime is the operating system and there is no need for Linux), I will speculate about possible future scenarios: A combination of an FPGA processor core and custom logic will provide all control tasks, slow and hard real-time, while keeping our convenient development environment for software such as Eclipse. I will illustrate my claims with designs for tasks such as low-latency PID controllers running at several dozen MHz, sub-nanosecond resolution timing, motion control, and a versatile I/O controller–all implemented in real-time Java and on exactly the same hardware, just with different connectors.

  For PETRA III, the high-brilliance third-generation light source being built now at DESY in Hamburg, Germany, we have established a new hardware development standard for controller designs. It includes communication on the fieldbus level, hardware interfacing to fieldbuses, and a communication application software layer for device firmware. The CAN bus and CANopen protocol were chosen as a primary fieldbus standard, and three branches of generic CANopen-compliant interfacing modules were designed for rapid controller hardware development. For fieldbus management, configuration, and integration with the TINE control system*, the generic TICOM (TINE-Based CANopen Manager) software was written. This document gives an overview of our fieldbus hardware development standard and of the key features of TICOM. It also describes the first applications built on top of the standard.

WPPB36 Ripple Diagnostic on BESSY II Power Supplies controls, storage-ring, dipole, background 466

  Keeping the ripple of power-supply currents within the specification limits is crucial for the beam stability of the BESSY storage ring. Malfunctioning or aged electronic devices cause an increase of output ripple over the years. This increase is hardly noticed by the operator or operation analysis because the slow integrating AD converters for the current readbacks filter out the ripple. Furthermore, it is almost impossible to find the connection between certain beam movements or beam noise and the faulty power supply causing it. To improve this situation, ripple information for every power supply is required within the control system. The latest series of the CAN bus-connected power-supply interface cards used at BESSY provide an additional fast AD converter. With a sampling frequency of 83.5kHz, this ADC samples ripple information over one period of the mains voltage. The results are transferred over the CAN bus to the EPICS-based control system and can be processed in the usual ways. Using this setup, even temporarily increased ripple can be detected without complex measurement methods.  
 
ROAB04 Experience of Developing BEPCII Control System controls, cryogenics, synchrotron, vacuum 511
 
  • J. Zhao
    IHEP Beijing, Beijing
  The project of upgrading the Beijing Electron Positron Collider (BEPC) to the BEPCII was started in autumn of 2001, and the goal is to reach a higher luminosity, 1*1033cm-2s-1. The first beams were stored in the Storage Ring in November 2006, and the e+/e- beams successfully collided in March 2007, which is an important milestone of the BEPCII. The BEPCII control system has rebuilt with the “standard mode” and EPICS, which has 20,000 channels and about 30 VME IOCs for equipment control and high-level applications. The control system was put into operation in November 2007, and the system development has followed its schedule and finished on time. In the past few years, we went through the design stage, R&D stage, system development, testing, and installation and commissioning stages. This paper describes experiences and lessons of design and developing the system, including the design considerations, selection of standard hardware and software, building of the development environment, and what we have done in the user requirement, R&D, and other stages. The paper also discusses project management issues, such as interface definition, collaborations, people training, and so on.

  We present the development of transverse orbit stability control at Diamond. We discuss the low latency feedback loop required to effectively suppress high-frequency noise, which informs the choice of network topology and processing units. We explore the use of the field-programmable gate array in the Libera beam position monitor as a communication controller and the vector unit of the PowerPC G4 in the compensator. System models and results from preliminary tests on the machine are shown.  
 
RPPA23 Initial Design of a Global Fast Orbit Feedback System for the ALBA Synchrotron vacuum, electron, feedback, sextupole 561

  This paper presents the initial design of the Global Fast Orbit Feedback (FOFB) system for the ALBA Storage Ring. The FOFB system is designed to reach a submicron stability of the electron beam working at frequencies of at least 100 Hz. It compensates the small perturbations produced by vibrations, electromagnetic noise and changes in the gap or phase of the insertion devices, etc. A description of the model is shown. The different subsystems have been identified and modeled: the BPM processor, the iron lamination and the vacuum chamber. The power converter supplies for the correctors play an important role in the system, and they have been designed (strength, resolution, bandwidth, voltage output) accordingly with the FOFB requirements. We have also studied the latency of the system (communication network, processing times). The orbit correction is computed by a PID controller. The simulations of the closed loop response show a damping of the perturbation between 0 and 100 Hz, although the system also introduces a small amplification of the noise just after this bandwidth. Finally the paper presents the initial design of the hardware architecture of the FOFB system.

  The Control System of J-PARC 3GeV RCS is configured based on Database, which is comprised of Component Data Management DB (Component DB) and Data Acquisition DB (Operation DB. Component DB was developed mainly to manage the data on accelerator components and to generate EPICS records automatically using the data. Presently we are testing the reliability of DB application software at Linac operation. Later most Linac EPICS records are generated from DB, and we are able to operate Linac with very few problems. Operation DB collects the two kinds of data. One is EPICS records data, and the other is synchronized data. Now we are testing the reliability of application software for EPICS records data collection, and we have confirmed that EPICS record data are corrected with very few problems. Later Linac EPICS records data are inserted in Operation DB from Linac Operation start. On the other hand, application software for synchronized data collection is now being developed, and we will test the reliability of this application software from comprehensive information on RCS operation. We report on the status of development for Database for Control System of J-PARC 3GeV RCS.

  The magnet power supply ramping synchronously is a fundamental procedure of the energy ramping of the BEPCII storage ring. The BEPCII has been put into synchrotron radiation operation (SR) (2.5GeV) research for 2 months after beams were successfully running in the Storage Ring with good beam performance. A software-based synchronization of the DAC setting on the power supplies is developed to achieve the relative magnet power supplies in the synchrotron ring ramped to the designed current synchronously. This paper introduces the schemes developed to perform energy ramping in the BEPCII storage ring and reports on the result of the operation carried out so far.

  The CERN accelerators’ controls infrastructure spans over large geographical distances and accesses a big diversity of equipment. In order to ensure smooth beam operation, efficient monitoring and diagnostic tools are required by the operators, presenting the state of the infrastructure and offering guidance for the first line support. The DIAMON project intends to deploy software monitoring agents in the controls infrastructure, each agent running predefined local tests and sending its result to a central service. A highly configurable graphical interface will exploit these results and present the current state of the controls infrastructure. Diagnostic facilities to get further details on a problem and first aid to repair it will also be provided. This paper will describe the DIAMON project’s scope and objectives as well as the user requirements. Also presented will be the system architecture and the first operational version.

  The amount of control data to be handled by the ALICE experiment at CERN is by a magnitude larger than in previous-generation experiments. Some 18 detectors, 130 subsystems, and 100,000 control channels need to be configured, controlled, and archived in normal operation. During the configuration phase several Gigabytes of data are written to devices, and during stable operations some 1,000 values per second are written to archival. The peak load for the archival is estimated to 150,000 changes/s. Data is also continuously exchanged with several external systems, and the system should be able to operate unattended and fully independent from any external resources. Much care has been taken in the design to fulfill the requirements, and this report will describe the solutions implemented. The data flow and the various components will be described as well as the data exchange mechanisms and the interfaces to the external systems. Some emphasis will also be given to data reduction and filtering mechanisms that have been implemented in order to keep the archive within maintainable margins.

  Orbit feedback system of the Taiwan Light Source (TLS) has been deployed for a decade. The loop bandwidth was limited by existing hardware. The system cannot remove perturbation caused by fast source. To improve orbit feedback performance, BPM system and corrector power supply are planned to upgrade within a couples of years. New digital BPM electronics will enhance functionality of the BPM system and replace analogy type BPM but due to limited resource, the BPM system will be a mixed type at this moment. The corrector power-supply is also replaced by high performance switching type power supply with wide bandwidth in the same time. It is expected that our upgrade will significantly improve performance of fast orbit feedback.

  For each control system of the Large Hadron Collider (LHC) experiments, there will be many processes spread over many computers. All together, they will form a PVSS distributed system with around 150 computers organized in a hierarchical fashion. A centralized tool has been developed for supervising, error identification and troubleshooting in such a large system. A quick response to abnormal situations will be crucial to maximize the physics usage. The tool gathers data from all the systems via several paths (e.g., process monitors, internal database) and, after some processing, presents it in different views: hierarchy of systems, host view and process view. The relations between the views are added to help to understand complex problems that involve more than one system. It is also possible to filter the information presented to the shift operator according to several criteria (e.g. node, process type, process state). Alarms are raised when undesired situations are found. The data gathered is stored in the historical archive for further analysis. Extensions of the tool are under development to integrate information coming from other sources (e.g., operating system, hardware).

  Many electronic books exist for logging the activity of an accelerator, but all of them are basically a translation of a paper book in an electronic format, with some extra features coming from the usage of a database for storing the information. SPARCbook is based on PostgreSQL, an open source database. A new, nice GUI has been developed for manually inserting data (both text and pictures) in the logbook and retrieving the old information, using several filters like date, author, or type of information. This GUI has been developed using HTML, PHP, and JavaScript, and it is quite similar to GUIs of already existing electronic logbooks. The peculiarity of SPARCbook is that it is also possible to insert information in the book from the control system of the accelerator, automatically or after a human decision. The SPARC control system is a distributed system, developed using LabVIEW, based on PCs and real-time CPUs. Information, tables, and graphs can be submitted from each CPU and from the central control system to SPARCbook making a query to PostgreSQL via TCP. That makes the system really powerful because any commercial CPU has TCP capability.

  Operation of an accelerator requires the efficient and reproducible execution of many different types of procedures. Some procedures, like beam acceleration, magnet quench recovery, and species switching can be quite complex. To improve accelerator reliability and efficiency, automated execution of procedures is required. Creation of a single robust sequencing application permits the streamlining of this process and offers many benefits in sequence creation, editing, and control. In this paper, we present key features of a sequencer application commissioned at the Collider-Accelerator Department of Brookhaven National Laboratory during the 2007 run. Included is a categorization of the different types of sequences in use, a discussion of the features considered desirable in a good sequencer, and a description of the tools created to aid in sequence construction and diagnosis. Finally, highlights from our operational experience are presented, with emphasis on Operations control of the sequencer, and the alignment of sequence construction with existing operational paradigms.

  TINE (Three-fold Integrated Networking Environment) has been the Control System in use at HERA for some time, plays a major role in the Pre-accelerators at DESY, DORIS, FLASH, PITZ (Zeuthen), EMBL-Hamburg, GKSS-Hamburg, PF Beamline (KEK), and is the designated control system for the new third-generation light source PETRA3. TINE has always emphasized both performance and flexibility. For instance, using the multicast capabilities of TINE, state-of-the-art, near real-time video transmission is possible. At the same time, developers have a large toolkit and variety of software solutions at their disposal, and in general on their favorite platform and programming language. Code-generation wizards are available for rapid development of TINE servers, whereas intelligent GUI components such as ACOP(*) aid in the development of either “rich” or “simple” client applications. The most recent major release brought with it a bundle of new features and improvements. We give here an overview of the TINE control system in general, what’s new in particular, and focus on those features not available in other mainstream control systems, such as EPICS or TANGO.
