The development of a high power CW electron linear accelerator was started in 1989 to study the feasibility of nuclear waste transmutation. The accelerator (10MeV, 100mA peak current, 4 ms pulse width, 50 Hz repetition) is dedicated machine for development of the high current acceleration technology in future need. It is necessary to develop the system which controls high power RF in order to stably accelerate the high current beam. Then, We have developed the interlock system for protecting accelerating tube from high current beam in time of trouble of high current beam and high power RF. We have succeeded in the development of the system so as to be able to choose interlock elements corresponding to the operating condition. Using the beam of the low electric power, the synthetic interlock system was tested. The beam was cut off at 3.5sec, after the interlock operated.
