Radiation resistance of vacuum equipment in J-PARC RCS

Mio, Keigo; Ogiwara, Norio; Marushita, Motoharu*; Arai, Hideyuki*; Goto, Keiichi*

Intense of radiation fields will be expected since large intensity proton beam current of J-PARC 3GeV RCS (Rapid-Cycling Synchrotron). -ray irradiation tests of vacuum system equipment were carried out to evaluate radiation resistance for RCS. Requirement of radiation resistance of vacuum equipment is assumed as 10 MGy. -ray irradiation examination has been done to select the vacuum equipment. As a result, cooling-fan, feed-through-connector, baking heater, piping sealants have been shown to have radiation resistance as 10 MGy. Dry scroll vacuum pump was shown as only 1 MGy from the restriction of the material of the chip seal (Teflon).
