The Electron Cyclotron Maser as a High-Power Travelling-Wave Amplifier of Millimeter Waves.

Abstract

The electron cyclotron maser instability has been exploited as the basis for a new type of travelling wave amplifier which operates at unusually high power levels at millimeter wavelengths. The first experimental model of this amplifier has been operated at 35 GHz and has demonstrated a stable gain of 17 dB and an output power of 10 kW (unsaturated). The gain was linear over a dynamic range > 30 dB. The absolute value of the gain and its dependence on current and magnetic field were in excellent agreement with theoretical calculations. Bandwidth and saturated power have yet to be measured directly but no fundamental problems were observed which will prevent successful achievement of the design predictions (viz., bandwidth approximately 10%, power on the order of 100,000 watts, efficiency > 10%).
