Numerical simulation of a Gyro-BWO with a helically corrugated interaction region, cusp electron gun and depressed collector

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

The gyrotron backward wave oscillator (gyro-BWO) is an efficient source of frequency-tunable high-power coherent radiation in the microwave to the terahertz range. It has attracted significant research interest recently due to its potential applications in many areas such as remote sensing, medical imaging, plasma heating and spectroscopy. A gyro-BWO using a helically corrugated interaction region (HCIR) has achieved an even wider frequency tuning range and higher efficiency compared with a conventional gyro-BWO with a smooth-bore cavity. This is due to the existence of an “ideal”eigenwave in the HCIR with a large and constant group velocity when the axial wave number is small.
