  J-PARC accelerator complex comprises Linac, 3-GeV RCS (Rapid Cycle Synchrotron), and 30-GeV MR (Main Ring). The J-PARC is a joint project between JAEA and KEK. Two control systems, one for Linac and RCS and another for MR, were developed by two institutes. Both control systems use the EPICS toolkit, thus, inter-operation between two systems is possible. After the first beam in November, 2006, beam commissioning and operation have been successful. However, operation experience shows that two control systems often make operators distressed: for example, different GUI look-and-feels, separated alarm screens, independent archive systems, and so on. Considering demands of further power upgrade and longer beam delivery, we need something new, which is easy to understand for operators. It is essential to improve reliability of operation. We, two control groups, started to discuss future directions of our control systems. Ideas to develop common GUI screens of status and alarms, and to develop interfaces to connect archive systems to each other, are discussed. Progress will be reported.

  The Control System for IFMIF/EVEDA* accelerator prototype consists of six subsystems; Central Control System (CCS), Local Area Network (LAN), Personnel Protection System (PPS), Machine Protection System (MPS), Timing System (TS) and Local Control System (LCS). The IFMIF/EVEDA accelerator prototype provides deuteron beam with power greater than 1 MW, which is the same as that of J-PARC and SNS. The PPS is required to protect technical and engineering staff against unnecessary exposure, electrical shock hazard and the other danger phenomena. The PPS has two functions of building management and accelerator management. For both managements, Programmable Logic Controllers (PLCs), monitoring cameras and limit switches and etc. are used for interlock system, and a sequence is programmed for entering and leaving of controlled area. This article presents the PPS design and the interface against each accelerator subsystems in details.
