In the view point of the radiation, the electric motor is one of possible weak points of the rotation target. We prepared a commercially available small rotation target with an electric motor. The target was irradiated with 0.63 MGy in the Co-60 gamma-ray irradiation facilities. The dose of 0.63 MGy corresponds to about one ILC (International Linear Collider) year at the electric motor of the ILC positron production target. After the irradiation we tested the rotation of the target and no problem was found.}, title = {Radiation Tolerance Test of the Rotation Target for the J-PARC Beam Scraper and the ILC Positron Source}, year = {2017} }
