Superconducting radio frequency photoinjector (SRF gun) provided a promising approach. However, some limitations occur caused by electron multipacting in the cathode vicinity, which prevent the superconducting radio frequency photoinjector (SRF gun) from maximum productivity. The aim of this thesis is to develop a new design of the photocathode channel.
