J-PARC CONTROL TOWARD FUTURE RELIABLE OPERATION

The J-PARC accelerator complex comprises proton LINAC, 3-GeV RCS, and 30-GeV MR. 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 2006, beam commissioning and operation have been successful. The current status of J-PARC control structure is given. Components are introduced and reviewed with reliability issues: A plan to develop new GUI applications for operators is given.
