Abstract
Summary form only given. An electron beam source is under development at Los Alamos National Laboratory. We outline the generation of the electron beam in a plasma cathode electron (PCE) source. Our PCE source was created using 1.5 kW of microwave power at 2.45 GHz delivered in a static magnetic field of 875 Gauss. We were able to drive electron beams of greater than 100 A in our source with very high beam efficiencies by biasing the ECR source chamber to -140V. Diagnosis of the beam was done using spectroscopy and electric probes. We discuss both the generation method and the diagnostics we used in this experiment.
