We are developing a high-gradient, THz-driven electron gun. THz-frequency accelerator structures can enable the development of compact, bright, and efficient particle sources. Our two cell standing-wave gun is powered by a 110 GHz gyrotron and will produce 350 keV electrons with 500 kW of input power. The field emission cathode is a copper tip located in the first cell. High power measurements will include diagnostics to measure the energy spread, charge, and size of the resulting bunch.
