The input coupler is an important component for a microwave amplifier. In this paper, a
sidewall single-hole input coupler for a W-band gyrotron traveling-wave amplifier that …

A quasi-optical mode converter in the form of a corrugated horn has been designed through
numerical simulations, manufactured and experimentally measured for application in W …

A novel thermionic cusp electron gun operating in the temperature-limited regime that
produces a large-orbit electron beam through a nonadiabatic magnetic-field reversal was …

This paper presents the experimental study of microwave pulse compression using a five-
fold helically corrugated waveguide. In the experiment, the maximum power compression …

This study proposes a mode-selective circuit to suppress the competing modes in a TE 01
gyrotron backward-wave oscillator (gyro-BWO). The circuit, also functioning as an interaction …

The frequency agility of a W-band gyrotron travelling wave amplifier (gyro-TWA) was
demonstrated by the amplification of a frequency-swept input signal (chirp signal). The gyro …
