Study of Gain in C-Band Deflection Cavities for a Frequency-Doubling Magnicon Amplifier

Abstract

We report an experimental study of the gain between two half- wavelength, 5.7 GHz TM 110 pillbox cavities, separated by a quarter-wavelength drift space, and powered by a 170A, 500 keV electron beam immersed in an 8.1 kG magnetic field. These cavities constitute the first section of a planned multicavity detection system, whose purpose is to spin up an electron beam to high transverse momentum for injection into the output cavity of a frequency- doubling magnicon amplifier. We have observed a gain of approx. 15 dB in the preferred circular polarization, at a frequency shift of approximately -0.18%, and a gain of approx. 3 dB in the opposite circular polarization, at a frequency shift of approximately +0.06%. These results are in good agreement with theory. Magnicon, C-Band, Gyrocon, Amplifier.
