advances have made the development of pulsed electron sources in this parameter range attractive as well. Pulsed sources operate with space charge limited cold cathode emission on the microsecond or submicrosecond time scale. As a result, the dose rates are much higher than currently available. A design for a 10 MV, 100 kW or greater accelerator for large area electron beam irradiation or for bremsstrahlung conversion is described. The design is based on pulse transformers to generate megavolt, microsecond pulses, saturable magnetic core switching to compress to shorter pulse lengths, pulse forming line adder techniques to transform to 10 MV, a magnetically insulated cold cathode diode for electron beam formation. The status of these various technologies is reviewed.

The purpose of this program was to produce a control and protection architecture and functional circuits that would work with all three power stage topologies. The requ i rements f or t he t hree exi sti ng pow er stages were determined. The three existing control and protection circuits were? analyzed. An IC technology study was performed to'determine the optimum technology and fabrication method for SRI contro1 and protection circuits. A contro1 and protection architecture uti1izing common functiona1 circuits that wou1d work wit h t he t hree existing topologies was developed and block diagrams drawn. The functional tasks were portitioned into five custom parts. The requirements for the custom parts were described. A study was performed to assess the potential present and future functions for a mi croprocessor in a series
