Purchase was made of necessary equipment for the construction of a high-current betatron experiment. The purchase included ferrite isolation cones, silicon steel isolation cones, HV constant-current power supplies, and HV unregulated power supplies; a paper describing use of this equipment is attached. Generation and propagation of high-brightness electron beams from a magnetically crowbarred injector were studied. Tests of a 300-keV electrostatic electron beam injector with a magnetic crowbar switch are described. The saturable-ferrite-core switch allows generation of a constant-voltage, 80 ns pulse directly from a Marx generator. Inductive isolation in the switch permits direct access to the high-voltage electrode for thermionic or active plasma cathode experiments. The pulse modulator can drive a 1.5-kA load. A high-brightness 290-A beam from a felt plasma-emission cathode was extracted and propagated in vacuum. Because of the reliability of the magnetic-crowbar switch, more than 500 shots were accumulated on the cathode at over 1 kA/2 sq cm with no degradation of the output.
