First results of a cw industrial FEM
Abstract
We have designed and constructed a cw FEM system capable of operating as an oscillator or an amplifier in the X-band frequency range. This system utilises a 130 keV, 13 mA electron beam which is cw (rather than pulsed) and a 1.52 m, 38 mm period wiggler constructed from ferrite permanent magnet bars. The gain of this system as an amplifier has been measured as a function of the electron beam accelerating voltage and current level, using an external microwave source in the range 7.6-8.9 GHz, and the output power of the system as an oscillator has been measured. This paper tabulates the results and compares them to theoretical models.
