TL;DR: A quasi-optical mode converter for a 0.42 THz, TE17,4 mode pulsed gyrotron oscillator is designed, fabricated and tested in this paper.

TL;DR: In this paper, the effect of the electron beam quality, including the variation of the velocity spread, the guiding center radius spread, and the pitch factor when the operating frequency of a 250-GHz TE52 mode continuously frequency-tunable gyrotron used for dynamic nuclear polarization (DNP) enhanced nuclear magnetic resonance (NMR) spectroscopy is tuned by changing the operating voltage or the operating magnetic field ${V}_{0}$, on the operating frequencies, the frequencytunable range and the beam-wave interaction efficiency, has been studied based on a self-cons

TL;DR: In this paper, a 500 GHz TE85 mode continuously frequency-tunable gyrotron has been designed, fabricated and investigated experimentally, where the operating frequency is tuned by means of adjusting the operating magnetic field or the beam energy.

TL;DR: In this paper, a method was proposed to efficiently separate radiations from a dual-frequency operation gyrotron, where the operation modes TE02 and TE04 were converted into linearly polarized Gaussian beams, and the theoretical predictions of the power conversion efficiency were 85% for TE02 mode and 90% forTE04 mode, respectively.

TL;DR: In this paper, the effect of slightly up-tapered sections in a multisection gyrotron cavity on the resonant frequency and the quality factor is investigated in detail.
