Abstract

We present design methodology for high power microwave switches. Among all possible applications for such a switch we emphasize the design parameters for application to the pulse compression system associated with the Next Linear Collider (NLC). The switch is based on the excitation of a plasma layer within a silicon wafer by either a laser or an electron beam. We investigate problems associated with high power operation of such a switch. Mainly, we explore solutions to the problems of thermal runaway, avalanche breakdown, photo-emission, and secondary emission. Different design methodologies are presented
