Abstract

A photocathode RF gun system was built to develop the electron source for the Thomson scattering X-ray source at Accelerator laboratory of Tsinghua University. The system consists of a BNL/ATF type 1.6 cell S-band RF cavity, a solenoid for emittance compensation, a laser system and some simple equipments for beam diagnosis. The status of the system is introduced in this paper, and the first beam measurements of the photocathode RF gun, including the dark current, transverse beam profile, charge and quantum efficiency is also reported.
