【Abstract】 It is important for HIRFL to improve the whole operation level if SSC accelerating voltage can be increased. In order to increase the voltage, it should firstly analyze the maximum voltage that SSC RF cavity can achieve in theory. SSC RF cavity was thoroughly analyzed and the main parameters of the cavity were obtained by using a three-dimensional electromagnetic calculation code. Based on the simulation results and the practical operation parameters the possibility of increasing the voltage is discussed. Since the little power loss in high-power operation may affect the stability of the cavity-amplifier system, the power coupling system was also analyzed. The limit of power reflection is got and the improving methods are discussed too.更多还原
