Three-dimensional particle simulation research on relativistic diffraction generator

A coaxial corrugated reflector and smooth drift segments structure of relativistic diffraction generator were studied using the full three-dimensional particle simulation software CHIPIC. The influences of the drift segments and reflector on the output power were analyzed. The relationship between the reflector position and the output power was explored. The simulation results show that appropriate reflector and drift segments can greatly improve the output power. After optimization of the structure parameters, when the input voltage was 480 kV, the average output power achieved 774.5 MW and the average power efficiency attained 32.3%.
