Development of a Novel Superconducting RF Photocathode Electron Gun*

Over the past year Advanced Energy Systems Inc. and Brookhaven National Laboratory have undertaken a program to develop a Superconducting Photocathode Electron Gun utilizing a unique cathode concept. The cathode concept is much simpler than many other approaches and should avoid many complications which might otherwise be encountered. This cathode concept does not utilize an insert of any kind and is fully integrated with the Nb cavity. The results of experiments which demonstrate the feasibility of the cathode concept will be presented. We will review the important gun design parameters, discuss how they play against each other, and present results of an optimization of the design. Anticipated beam output parameters will be given, based on the optimized design and experimental results. Finally we will review our plans to continue the development program. This program will include the design and fabrication of the cavity and associated cryostat at Advanced Energy Systems Inc, integration of the entire system, and testing of the full system at BNL.
