Abstract :
It was success to develop the radiation resistant components using for beam collimator. Turbo molecular pump could be operated more than 15 MGy of gamma ray irradiation dose. Stepping motor developed at JAERI could be operated with good performance in the gamma ray dose of more than 70 MGy. PEEK sheathed cables and connector have kept good performance during gamma ray irradiation more than the dose of 10 MGy. It was cleared that the function of the heat pipe disappeared at 30 kGy gamma ray irradiation dose.
