Design of a compact Cherenkov Free-Electron Laser

摘要

Design of a Cherenkov free-electron laser operating in millimeter wave range was carried out as a test bench for a compact terahertz radiation source. A CW output of 1.8 W is expected at the frequency of 46.4 GHz with 50 keV electron beam. The experimental apparatus consists of Spindt-cathode, double-silicon-slab resonator and super-conducting coil.
