J-PARC is a large scale facility of the proton accelerators for the multi-purpose of scientific researches in Japan. This facility consists of three accelerators and three experimental stations. Now, J-PARC is under construction, and LINAC is operated for one year, 3GeV synchrotron has just started the commissioning in this October the 1st. The completion of this facility will be next summer. The control system of accelerators established fundamental performance for the initial commissioning. The most important requirement to the control system of this facility is to minimize the activation of accelerator devices. In this paper, we show that the performances of each layer of this control system have been achieved in the initial stage.

The main purpose of Personnel Protection System (PPS) is to protect people from radiation exposure. From the viewpoint of it, important features of the Japan Proton Accelerator Research Complex (J-PARC) are (1) the beam power as high as 1MW, and (2) a lot of beam-line entrances apart from the main control room. The first feature requires the beam interlock function of PPS to be more reliable than ever. The second one is dealt with the access control function of PPS, with which the remote access control from the central control room is enabled. In this paper, we report the beam interlock and access control functions of the PPS.
