Abstract

Results are reported on the experimental and theoretical performance of a dielectrjc Cherenkov maser amplifier. The amplifier is designed to work in the TM01 mode of a cylindrical dielectric lined waveguide. In a low voltage low current (200 kV 100A ) experiment results indicate that the device has operated as an amplifier at a frequency of 9. 8 GHz. The rf input of the amplifier was provided by a tunable (9-10 GHz) 10 kW magnetron. An average power gain of approximately 0. 6 db/cm over a 21 cm interaction length was measured using electron beam parameters of 190 kV 90 amperes and a beam pulse length of 1 . Ls. Preliminary results of the scale up of the experiment to a system driven by a 700 kV to 1 MV 3 kA 100 ns electron beam with rf input provided by a tunable (8. 4-9. 6 GHz) 200 kW magnetron indicate a power output of 280 MW at 8. 6 GHz. However due to the large amount of feedback in the system the device might more appropriately be described as a frequency locked oscillator. 1.
