  Control System for IFMIF/EVEDA* prototype accelerator 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 prototype accelerator provides deuteron beam with the power more than 1 MW, which is as same as that in cases of J-PARC and SNS. Then, the PPS is required to protect technical and engineering staff against unnecessary exposure and the other danger phenomena. The MPS and the TS are strongly required a high performance and precision to avoid radio-activation of the accelerator components. To realize these requirements, the PPS designed that Programmable Logic Controllers (PLCs) are used mainly, and a sequence is programmed for entering and leaving of controlled area and etc. Hardware and logic sequences for the MPS are designed to realize the beam inhibition time within 30 micro-seconds. The TS prototype modules were designed and tested using 10 MHz master clock and 100 Hz reference trigger. This article presents the PPS, MPS and TS design in details.
