The gyrotron traveling-wave tube (gyro-TWT) is a wideband version of gyrotron amplifiers, which produce pulsed or continuous-wave radiation in the millimeter-wavelength band at a power level that exceeds the powers produced by conventional TWTs with slow-wave structures and rectilinear beams by 1–2 orders of magnitude. Since 1996, researchers at the Institute of Applied Physics of the Russian Academy of Sciences (IAP RAS) have been developing the concept of the gyro-TWT based on the use of a waveguide with a helically corrugated surface, which changes the dispersion of one of the eigenmodes in a circular waveguide radically. In this paper, we discuss several problems that arise in implementation of such devices, which many years of experimental studies have revealed, present the parameters of gyro-TWTs developed with allowance for specific applications of their end users, and discuss lines of further perfection of such amplifiers.

在 IAP Ras 研究带有螺旋波纹波导的回旋管行波管：结果和前景

回旋行波管（gyro-TWT）是回旋放大器的宽带版本，它在毫米波波段产生脉冲或连续波辐射，其功率水平超过具有慢波结构的传统行波管产生的功率和直线光束 1-2 个数量级。自 1996 年以来，俄罗斯科学院应用物理研究所 (IAP RAS) 的研究人员一直在开发基于使用具有螺旋波纹表面的波导的陀螺-TWT 的概念，该波导改变了其中一个的色散圆形波导中的本征模从根本上。在本文中，我们讨论了在实施此类设备时出现的几个问题，多年的实验研究表明，
