Investigation of a Photoconductively Switched, Radial Transmission Line Accelerator

Abstract

This paper analyzes the use of GaAs photoconductive switches and a 2 m radius. radial transmission line section to generate acceleration gradients of up to 50 MV/m for nanosecond duration. 4 kA beam current pulses. The proposed acceleration system is much simpler and easier to precisely synchronize than the annular electron beam "wake field" accelerator designs proposed elsewhere. The design of an accelerator module with annular Blumlein line pulse generator. GaAs switches and associated optical systems. ferrite isolation of the backward wave. and solid state optical control is presented. In addition. the radial wave equations are solved using the Method of Characteristics and computer solutions compared with experimental voltage amplification data from a 4 m diameter radial line fabricated at UT Arlington. A system point design is presented to indicate the parameters of the component requirements and the system performance parameters.
