Abstract : 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. 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.
