Description
The authors discuss two studies of cyclotron autoresonance maser (CARM) amplifiers underway at M.I.T. They differ both in frequency and in the technologies employed. The 35GHz amplifier uses a 1.5MeV,260A,30ns electron beam from a field emission (explosive) cathode energized by a Marx type, Physics International Pulserad accelerator. The entire system is immersed in a uniform, pulsed magnetic field 7kG. Measurements give a small signal gain of 90dB/m, a saturated power output of 10MW and an electronic efficiency of 3%. The 140GHz amplifier under development will employ a 450-700kV, 30A, 1μs electron beam from a Pierce-type gun driven by a high-voltage, long-pulse modulator. The magnetic field (--25kG) in the CARM interaction region will be produced by a superconducting magnet. Theoretical investigations of CARM efficiency, efficiency enhancement by magnetic field tapering, and amplifier stability are also being carried out
