High-brightness, superconducting continuous wave accelerators presently use an electron source that is separated from the initial accelerating modules. Significant gains in compactness, beam brightness, efficiency, and reliability could be realized by developing a superconducting gun where the photocathode is an integral part of the initial accelerating cavity. This project will develop a system that eliminates the need for a separate electron gun by utilizing the cavity endwall itself as the integral photocathode. Using existing cryogenic, laser, radio frequency, and diagnostic equipment, the achievement of superior brightness and beam quality from the gun will be demonstrated. In Phase I, the beam dynamics and thermal/mechanical design of a multi-cell, superconducting radio frequency cavity with an integral photocathode will be completed. The design will yield a high-brightness, high quality electron beam at the output of the injector system.
Commercial Applications and Other Benefits as described by the awardee: A superconducting photocathode gun would be an ideal source for superconducting electron accelerators and free electron lasers. Additional applications would ensue if the gun can be further developed towards the higher power required for commercial material processing and military free-electron laser applications, because of the improved cost, performance, and efficiency.
