Photoconductive semiconductor switch (PCSS) driven linear induction accelerator (LIA) cavity

This poster describes experiments to test the concept of actively driving a 20-40 MHz linear induction accelerator with a pulsed power system using photoconductive semiconductor switches (PCSS). An rf-modulated regenerative laser is used to trigger GaAs switches which connect a constant current source to a pair of linear induction cavities. The switches must stand off 500 kV and interrupt 2.5 - 5 kA. Multiple pulse and single pulse test results with one switch driving one cavity are shown. 11 figs.
