  The dozen of wide-band beam diagnostics sensors such as integration current transformer, faraday cup, and wall current monitors were used in SSRF(Shanghai Synchrtron Radiation Facility) Linac and transport line to measure bunch shape and charge. Few hundreds MHz bandwidth required very high speed digitizer like digital sampling scope. On the other hand SSRF control system was built on EPICS platform. So Windows PC based Tektronics scope, which equipped with TekVISA interface, Shared Memory IOCcore EPICS interface, and Labview application was chosen to do this data acquisition. The details of software design and the performance evaluation results for TDS7104 and DPO7054 will be described in this paper.

  The Petawatt High Energy Laser for Ion eXperiments, http://www.gsi.de/forschung/phelix/indexe.html, will offer the unique combination of a high-current, high-energy (GeV/u) heavy-ion beam with a powerful laser beam thus providing the opportunity to investigate a variety of fundamental science issues in the field of atomic physics, nuclear physics, and plasma physics. The PHELIX Control System (PCS) is based on the CS framework, http://wiki.gsi.de/cgi-bin/view/CSframework/WebHome. About 35 additional classes were developed for the PCS and ~250 objects are running distributed on 13 PCs publishing ~10000 process variables. The PCS has been upgraded to version 3.0 recently. In CS 3.0 the entire communication layer has been changed to DIM (Distributed Information Management), which is a light weight protocol for inter-process communication based on TCP/IP, http://www.cern.ch/dim. The PCS was redesigned to make use and profit from the concept of named services. Clients may receive information from a service (observer pattern) or may send a command to a server (command pattern). By these means the implementation of the PCS behaviour with hierarchical state machines was eased.  
 
TPPB08 Present Status of SSRF Control System controls, linac, power-supply, vacuum 178

    SINAP, Shanghai
  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.

  SSRF is equipped with various beam instrumentations, in which the Linac part has been working well since the start of the commissioning this year, and the booster and storage ring parts are still under implementation and commissioning. The commercial products were adopted to build this system as much as possible. The all-in-one electron beam position monitor processor, Libera, was used for whole facility to provide single-pass, first-turn, turn-by-turn, COD, and fast application beam position data. The Bergoz NPCT175 parametric current transformers were used for DC current measurement in the booster and storage ring. The various optical beam diagnostic systems, such as synchrotron radiation interferometers for precise beam-size measurement, the fast gated camera, and the bunch length monitor will be equipped in the dedicated diagnostics beam line. Data acquisition for beam instrumentation system should be a part of control system, developed on an EPICS platform. There are three kinds of Input Output Controllers (IOCs) used in diagnostics: VxWorks-based VME IOCs, Linux-based Libera IOCs, and Windows-based PC IOCs.

    SOLEIL, Gif-sur-Yvette
  For high-level applications development, SOLEIL adopted GlobalSCREEN, a professional Java SCADA, developed by the ORDINAL company*. This environment enables end users to quickly build user-friendly GUIs without writing any Java code and by drag-dropping reusable graphical components developed by the software control team. These components are made up on top of the ATK** library, which provides a rich set of graphical widgets, including scientific data visualization tools, and already encapsulating communication with the Tango software bus. This way, SOLEIL can allow its users to lay out their supervisory applications with a homogenous look and feel and benefit (as they are natively provided by GlobalSCREEN) from functionalities such as access right management, web access, and remote administration at a minimal development cost. An original organization has been set up to deal with this collaborative work between “pure software developers” and “occasional” supervision applications developers. The work organization, the software architecture, and the design of the whole system will be presented, as well as the current status of deployment at SOLEIL for accelerators and for beamlines.

TOPB03 The Evolution of the ELETTRA Control System controls, feedback, storage-ring, radio-frequency 265
 
  • L. Pivetta, C. Scafuri
    ELETTRA, Basovizza, Trieste
  The evolution of the ELETTRA control system is presented by focusing on the major technical upgrades. The ElETTRA control system has been in operation since 1993. The orginal control system architecture was based on a three layer design. A field bus connected the low level computers used to interface the accelerator devices whilst a ten megabit shared Ethernet network linked the middle layer computers to the servers and operator workstations. A first control system upgrade started in 1998 in order to dismiss the field bus and to provide more computing power. A couple of years later a major rework of the network infrastructure was carried out with the introduction of a switched Ethernet architecture. Starting from 2003, in view of the construction of a new booster injector for the storage ring and of the FERMI@elettra free electron laser, new control system hardware and software platforms have been selected. Driven by the additional necessity of cutting development and maintenance costs, the Tango control system has been adopted. The tools developed in order to effectively manage the integration and coexistence of the legacy and new control system are described.

  To bring electrons from the LINAC to the storage ring, much equipment must be triggered synchronously to the beam. The timing system provides the time base needed for this purpose. More than a simple clocks distribution system, it is a real network, broadcasting clocks and data all over the synchrotron. Data are used to send events to equipment: for example, injection of electrons inside the booster, extraction of electrons from the booster to the storage ring, or even triggering diagnostic equipment. The timing system is made up of a standalone CENTRAL system and several cPCI LOCAL boards. The CENTRAL system provides clocks and data and broadcasts them to the LOCAL boards through an optical fiber network. LOCAL boards are placed close to the equipment, and they provide delayed signals to trigger them. These delays can be precisely adjusted by the user, making the equipment synchronous with the electron beam. After a brief explanation of our needs, the presentation describes the timing systems (architecture, performance, etc.) used at SOLEIL. It also describes the results after a year of use: the good, the bad, and the truth (well, maybe).

  A booster synchrotron capable of ramping from 0.25 to 1.2 GeV was recently commissioned at Duke University as part of the High Intensity Gamma Source upgrade. The triggering and timing system uses a combination of software logic and triggers, digital delay generators, and hardware synchronizers to coordinate the linac injector, booster synchrotron and electron storage ring. The injection system has been commissioned with a short pulse photo-injector linac into a single booster RF bucket and to two booster buckets separated by about half the circumference. It has also been commissioned with a long electron pulse from the injection linac into all 19 buckets. The extraction system, combined with short pulse kickers, can extract any of the booster's 19 electron bunches in to any of the storage ring's 64 bunches. Ramping is controlled by programmable VME based waveform generators triggered from the timing system. The system offers flexibility for commissioning and operations and provides a simple interface to the operator.

RPPA17 A Physics Based Approach for Magnet Control in a Booster and Storage Ring controls, storage-ring, wiggler, quadrupole 553

  At Duke University, a booster synchrotron was recently commissioned as part of the HIGS upgrade. For the ramping magnet power supply controls, we followed an approach previously implemented for the Duke Storage Ring controls. The high-level operator interface is presented in terms of the physics quantities of the accelerator, i.e., the effective focusing strength of the magnets. This approach allows for a tighter integration of the control system with physics modeling programs and facilitates machine studies. The approach also simplifies operations of the accelerators by presenting an interface nearly independent of machine energy. For the booster, nonlinearities of the magnets, a result of its extremely compact footprint, are incorporated in to the low-level software while providing a high level of machine tunability. For the storage ring, feed forward compensations built on the effective strength of the magnets simplify tuning of the machine over a wide range of electron beam energies or wiggler settings. This approach provides for a good match to the diverse operational modes supported by the Duke Storage Ring.

  Applications Organizing Index (AOI) is a relational database tool that has been implemented at the Advanced Photon Source (APS) to aid in the management of more than 600 unique control system applications. AOI provides control system developers an intuitive view of and navigation links to the components that make up a single control system such as source code files, operator displays, process variables, work history notes, programmable components, validation procedures, drawings, and more. The foundation for the Applications Organizing Index tool is the collaborative effort between several Experimental Physics and Industrial Control System (EPICS) sites to build the common relational database schema for documenting large and complex particle accelerator control systems, Integrated Relational Model of Installed Systems (IRMIS). This paper describes the evolution of AOI as it became populated with APS control systems component data and as users’ requests for new features of AOI became apparent.
