Abstract

PURPOSE: To obtain a device capable of freely selecting the ion source according to a kind of ion generated, by providing a vacuum valve at one end of the accelerator tube, and a rotatable flange with a plurality of ion sources installed to one end of the vacuum valve.
CONSTITUTION: At one end of an accelerator tube 1, for irradiating an ion beam 6, is provided a vacuum valve 11 having a leak valve 10. To another end of the vacuum valve 11, is rotatably installed a rotary base plate 15 to which ion sources 12W14, having gas induction ports 22W24, valves 25W27 and electrodes 19W21, respectively, are fixed. When used the ion source 12, the rotary base plate 15 is rotated to locate the ion source 12 in the center of a fixed plate 16, subsequently the vacuum valve 11 is opened then with a gas inducted into the gas induction port 22, and the irradiation of ion is operated. After the irradiation of ion is finished, the valve 10 is opened to place the ion sources 12W14 under atmospheric pressure, thereafter, with an evacuation made, and the next ion irradiation operation is prepared.
