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

The use of radiation-resistant resins becomes increasing as vessels for irradiation experiments. Polyimide (Kapton) was used on surfaces in contact with water in our radiolysis experiments, but the obtained results were not same to that when glass vials were used. In this study, to investigate the effect of resin on water radiolysis, the amounts of dichromate reduction and H
O formation after gamma-irradiation were compared in the presence or absence of resin in the aqueous solutions. The presence of resins increased the reduction but hardly changed the formation. Therefore, the reduction caused by radiolysis in aqueous solution was suggested to be promoted by the presence of resins. The promotion was further studied using pulse radiolysis, etc.
