LLNL has asked the team to design and build a test bed to investigate the effects of various factors on the beam quality of an electron gun. The team has constructed a test bed prototype and aims to characterize the electron beam emitted from a photocathode as a function of the incident laser beam characteristics, the material of the photocathode, the distance between the photocathode and the anode, and the voltage difference between the photocathode and the Wehnelt.
