Paper Abstract

Experiments are underway to generate high power, long-pulse microwaves by the gyrotron mechanism in rectangular-cross- section interaction tubes. Long-pulse electron beams are generated by MELBA (Michigan Electron Long Beam Accelerator), which operates with parameters: -0.8 MV, 1 - 10 kA diode current, and 0.5 - 1 microsecond pulselength. Multimegawatt range microwave power levels have been generated. Adjustment of the solenoidal magnetic field is being studied for polarization control. Polarization power ratios up to a factor of 15 have been achieved. Electron beam dynamics, i.e. beam alpha (the ratio of the beam perpendicular velocity to the parallel velocity, vperp/vpar, are being measured by radiation darkening on glass plates. Computer modelling utilized the MAGIC Code and a single particle orbit code into which are injected a distribution of electron angles or energies. Both small- orbit and large orbit (rotating) e-beams are being investigated.
