In the J-PARC 3GeV proton beam transport facility (3NBT), proton beam profile monitor, halo monitor, loss monitor and proton current monitors are used as proton beam monitor. The electric signals from these monitors are converted to digital signal with ADC on CAMAC modules and monitoring with EPICS system through CAMAC controller CC/NET. At the 3NBT proton beam monitor system, these are monitored with frequency of 25Hz and all of these data are archived. In this report, we develop the EPICS system for 3NBT proton beam monitors and confirm the performance of the system. As a result, we can monitor and archive these proton beam monitor signals at 25 Hz with CC/NET and EPICS.

Times Cited Count：5 Percentile：35.25(Nuclear Science & Technology)The JT-60 control system based on workstation and VME-bus system features with UNIX system has been successfully performed at JT-60U advanced plasma experiment. The various hardware modifications and the adoption of the advanced plasma control algorithms have been continued to the JT-60 control system since its upgrade in 1991. The ZENKEI, supervisory control system, has entirely remodeled from its original 16 bits minicomputer and CAMAC system to the combination of workstation and VME-bus system configuration with Ethernet communication network system. The plasma control system executes real-time plasma equilibrium control command calculation within 250msec control cycle time. Each plant control subsystems are also modified along with same design concept to the ZENKEI. Currently, the minor modifications of the control system have been considered to realize longer pulse of discharge experiments without major change of the JT-60 equipment. Nearly 60 seconds of pulse length up to Ip=2MA, Bt=2T, PNBI=10MW(
30sec) plasma experiments will start from October in 2003.

Times Cited Count：7 Percentile：45.11(Nuclear Science & Technology)Data processing system in JT-60 has been used CAMAC widely for control and data acquisition of plasma diagnostic. However, it has passed over fifteen years from the operation, and the problem is caused for maintenance and function enhancement by the deterioration. Then, Mini-computer and microcomputer ,which control the CAMAC system were replaced workstation based on UNIX-OS, and these system were remodeled by developing the application software for screen control by GUI and for constructing environment of remote diagnostic through the network. In addition, CAMAC device driver for Linux has been developed in for next CAMAC control system.

On the JT-60 radio frequency (RF) heating system, the decrease in the activity ratio was a problem because of the deterioration of the control system. To improve the reliability, we replaced CAMAC system for a power injection control system, which was a main cause of the trouble, with the microprocessor system. And, a function of computer supported programming function of RF power injection form was introduced, which contributed to reduce a load of operators. Furthermore, personal computers with network communication were introduced to improve a maintenance ability of the control system. As a result, the activity ratio of the RF heating system was improved significantly.

Times Cited Count：5 Percentile：34.58(Nuclear Science & Technology)The present status of JT-60 control system is reported including its original design concept, the progress of the system and various modifications since JT-60 upgrade. This control system has features of a functionally distributed and hierarchical structure, using CAMAC interfaces at the beginning, which are replaced to versatile module Europe (VME)-bus interfaces later, and a protective interlock system composed of both software and hard-wired interlock logics. Plant monitoring and control are performed by efficient data communication through CAMAC highways and Ethernet with TCP/IP protocols. Sequential control of a plasma discharges are executed by a combination of a remodeled VME-bus system and a timing system. At real-time plasma control system and a human interface system have been continuously modified corresponding to the progress of JT-60 experiments.
