Initial Operation of a High Power, Frequency-Doubling X-Band Magnicon Amplifier.

Abstract

This paper reports the initial high power operation of a frequency doubling magnicon amplifier at 11.120 GHz. The deflection cavities operate at 5.560 GHz. The device is operating in a single pulse mode at 650 kV and 225 A, using a 5.5 -mm-diam. beam from a plasma cathode, at a magnetic field of 6.7-8.2 kG. In order to overcome a gain saturation problem in the deflection cavities caused by plasma loading, the penultimate deflection cavity is operated very close to self oscillation. The typical output pulse length is 100 nsec FWHM, and is limited by rf breakdown of the penultimate cavity. Based on the measured far field antenna pattern and absolute calibration of all microwave components, the measured output power is 14 MW (+/- dB), corresponding to an efficiency of approx. 10%.
