Abstract
Free-Electron Lasers (FELs) [1] are coherent sources of high-power electromagnetic radiation. In the microwave part of the spectrum, high efficiencies can be achieved at power levels in the multi-megawatt range. FELs can be operated as amplifiers or oscillators, and so have applications in a variety of areas ranging from electron cyclotron resonance heating (ECRH) to RF acceleration [2]. In this paper, results of the de- sign and operation of a 27 GHz Bragg resonator Free-Electron Maser (FEM) oscillator and a 35 GHz high-gain FEM amplifier are presented and discussed. The experiment is driven by a 700 kV, 900 Ω HV modulator, and operates with a pulse length of 1μs at power levels in the 1-3 MW range.
