Stable High Power Harmonic Gyro-Amplifier.

Abstract

Our second harmonic smooth bore gyro TWT, which generated a record breaking 207 kW and was stable without rf input, was found to be in good agreement with our large signal simulation code for an axial velocity spread of 14% and therefore improvement is anticipated through optimization of the MIG electron gun. an analytical theory of slotted harmonic gyro TWT amplifiers, which can be used to evaluate stability, has been described in a paper submitted for publication to the IEEE Trans. on Plasma Science's Special Issue on High Power Microwave Generation. A new mode selective interaction circuit has been fabricated for the slotted gyro TWT to improve its stability by employment of the slicing technique successful employed in our second harmonic smooth bore gyro-TWT.
