High Repetition Rate Electron Beam RF-Acceleration and Sub-Millimeter Wave Generation via a Free Electron Laser.
Abstract
An Radiofrequency linac has been constructed which is specifically designed for Free electron laser applications. The shunt resistance is moderate, thereby allowing the acceleration of relatively high beam currents (somewhat 1 A) which will result in moderate FEL gains (somewhat 10 dB). Numerical simulation of the single-cavity TM sub 010 linear accelerator has been performed to determine the optimum cavity length. For this value, optimally phased electrons cross the cavity in one half of the rf cycle. This length is dependent on both the input and desired output energies. For the calculations. 10 kV was chosen as the input electron energy and 725 kV as the output energy in order to amplify 94 GHz radiation with a 3.0 cm period wiggler.
