Paper Abstract

A high power, 140 GHz, cyclotron autoresonance maser (or CARM) amplifier is under development at M.I.T. Theory, simulations, and the experimental design are discussed. The experiment will employ a high voltage (450-700 kV) Pierce-type beam and a helical wiggler to produce the required elec-tron beam. The initial experiment will be carried out using a 450 kV electron gun; the second phase of the experimental program will employ a 700 kV electron gun. The results of two-dimensional simulations are presented. The CARM nonlinear bandwidth and the sensitivity of the CARM to velocity spread are discussed. The stability of the CARM amplifier to absolute instabilities has also been investigated, and the criteria for stable CARM amplifier operation are presented.
