Abstract

The purpose of this project is to design and optimize a rudimentary electron gun at a scale and cost that would be easily achievable in a home lab. For the electron gun to function properly, a high vacuum chamber was constructed from surplus components. A number of parts were custom machined including vacuum parts, power electronics, vacuum gauges and the cooling system. The gun consists of a thermionic cathode held at a high negative potential relative to a grounded anode. The system was characterized using a phosphor screen, a floating collector plate, and current-voltage measurements.
