one of the recent difficulty for the SRF gun. Thus, among the several ongoing investigations on this phenomenon, the experimental results indicates that the high MP current has been measured in the cathode [...] cathode unit of the SRF gun at Helmholtz-Zentrum Dresden- Rossendorf research institute. This reduces the efficiency of the SRF system operation by limiting the accelerating gradient in the cavity. Moreover [...] Moreover, it might cause an impair of RF components and distortion of the RF signal. The goal of this project is to develop a new cathode unit of SRF gun as a countermeasure to suppress multipacting. Approach
