Abstract :
A 4.5 MeV RF gun has been in operation at UCLA as a part of a 20 MeV linac. To improve the photoelectron beam parameters without changing the major characteristics of the driving laser and RF systems, a revised and extended version of the present RF gun has been investigated. The new gun consists of 6 full cells terminated at either end by one half cell each. The gun operates in π-mode at 2.856 GHz. Accelerating fields and mode structures have been studied, and based on this, particle dynamics has been simulated. An aluminum prototype has been built for cold tests. Description of the gun is presented along with initial computational and experimental results
