TPPB04 Applications of OPC at BEPCII controls, luminosity, collider, electron 166

  The run-time data and machine parameters of the BEPCII is distributed over different platforms and stored with different softwares. Some is stored in various SCADA logging files, and some is stored in the EPICS archiver files. Now the EPICS data are stored in Oracle. No general method was provided to access these data. The OPC technology can solve this problem. Originally based on Microsoft's OLE COM (component object model) and DCOM (distributed component object model) technologies, the specification defined a standard set of objects, interfaces, and methods for use in process control and manufacturing automation applications to facilitate interoperability. We have developed EPICS/OPC Server and Oracle/OPC Server. With the help of these two servers and SCADA OPC Servers, it’s easy to get the data mentioned above on a Windows system. This paper describes the development of the two OPC servers and OPC applications at BEPCII.  
 
TPPB18 Present Status of VEPP-5 Control System controls, injection, linac, damping 199

  As VEPP-5 moves to commissioning, its control system—CX—becomes more mature. CX is a distributed, networked control system based on a 3-layer "standard model." It has been used for VEPP-5 control since 2000; most hardware is CAMAC and CAN-bus. Currently most control programs have switched to modular plugin-based architecture, which significantly eases development of applications and enhances the whole control system integration. Large-data-size control hardware (such as digital oscilloscopes and CCD-cameras) is fully supported by CX now. E-logbook is currently being deployed, both as a web application and with direct support in control programs. GIS technology is being introduced to the control system, which opens many interesting possibilities.  
 
TPPB27 The New Control System for the Future Low-Emittance Light Source PETRA 3 at DESY: Sprinting to the Finish controls, booster, linac, synchrotron 217
 
  • R. Bacher
    DESY, Hamburg
  At DESY the existing high-energy physics booster synchrotron PETRA 2 will be transformed into a third-generation light source (PETRA 3). In addition, the technical systems and components of the pre-accelerators LINAC 2 and DESY 2 will be improved. Within the scope of this project, the control system and the front-end electronics will be upgraded. Besides a report on the current project's status, the paper emphasizes the basic conceptual ideas and discusses their implications and how they lead to novel features and development tools.  
 
TOPB04 Control System of the KEKB Accelerator Complex controls, linac, injection, factory 268

  The KEKB asymmetric electron-positron collider complex consists of 8-GeV Linac, high-energy and low-energy rings. Some of the resources were inherited from the previous TRISTAN project, and also they are shared with Photon Factory and PF-AR light sources. In order to realize the long lifespan of the system de-facto and international standard technologies were employed since the early stage, which have been efficiently operated. Several gateway methods were implemented to integrate heterogeneous sub-systems, which are gradually converted into EPICS. Scripting languages are employed for higher-level applications. The ever-evolving control system has enabled flexible and reliable beam operations at KEKB throughout the long period.

WPPB10 Virtually There: The Control Room of the Future controls, linear-collider, collider, laser 418

  Imagine the ILC is up and running. Electrons and positrons collide happily, and scientists are taking data. Suddenly there's a problem with one of the laser wires. All experts are at a meeting on a different continent, but the problem needs to be fixed immediately. Difficult? Not when there's a Global Accelerator Network Multipurpose Virtual Lab (GANMVL) in place. High-speed, high-resolution cameras would allow the faraway experts to look at the fault, a web-based portal would let them access the controls and tools of the system with a simple "single-sign-on" procedure. However, the virtual lab is not just about remote operation. In principle it is already possible to run a control room remotely. This system is radically different in that it takes into account the human aspect of teamwork around the world. The implications of a working virtual control room are enormous. It might revolutionise virtual collaboration in completely different areas. The paper presents the GANMVL tool and the results of the evaluation of the Virtual Lab in production environment and real operations.

RPPB10 Use of E-Logbook in VEPP-5 Control System controls, injection, linac, electron 624
 
  • D. Bolkhovityanov, R. E. Kuskov
    BINP SB RAS, Novosibirsk
  An electronic logbook (e-logbook) becomes a must for large experimental facilities not only during operation, but also at building and commissionning stages (where VEPP-5 is now). Unfortunately, the "market" of such products is almost nonexistent. So, the choice is narrow: either use some other lab's software (adapting it for local needs) or create your own one from scratch. We have chosen the former way and picked DOOCS e-logbook from DESY. Main changes concerned localization (since Russian uses cyrillic letters, not latin) and data feeding mechanism (due to different model of logging from applications). Integration with GIS and alarm system is being examined.
