  J-PARC accelerator complex consists of a proton linac (LINAC), > a Rapid Cycle Synchrotron (RCS), and a Main Ring synchrotron (MR). The commissioning of LINAC already started in November 2006, while the commissioning of Main Ring synchrotron (MR) is scheduled in May 2008. Most of the machine components of MR have been installed in the tunnel. Introduction of electronic modules and wiring will be made by the end of 2007. For the control of MR, the J-PARC accelerator control network was extended to include the MR related parts in March 2007. IOC computers (VME-bus computers) for MR will be introduced in 2007. In addition, more server computers for application development will be also introduced in 2007. This paper reports the status of development for the J-PARC MR control system.

  A commercial measurement instrumentation (WE7000) is used at J-PARC LINAC, to measure beam current from SCT (Slow Current Transformer), beam energy from FCT (Fast Current Transformer), beam position from BPM (Beam Position Monitor), beam size from WSM (Wire Scanner Monitor), or beam loss from BLM (Beam Loss Monitor). The WE7000 is a module-type measurement station, and supports network-based data transmission and communication. A control system has been developed under EPICS framework for the beam diagnostic system to control all WE stations. A waveform signal from a SCT, a FCT, a BPM, a WSM, or a BLM is digitized in a WE7000 station and sent to an EPICS IOC. All signal voltages are calculated inside IOC from a raw digital count. Some physical variables are calculated from the signal voltages including beam current, beam position, and beam phase and beam energy. An EPCIS device driver was reutilized for the data acquisition. The GUI applications for data displays have been developed by using EPICS extensions tools. The current status is reported in this paper about the beam diagnostic system control.

  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.
