国际热核聚变装置用回旋管的现状及技术分析

摘要

Gyrotron is one of the most promising high-power millimeter-wave and terahertz source. The configuration and operating mechanism of gyrotron oscillator are briefly introduced. The state-of-art and developing trend of 110 GHz, 140 GHz and 170 GHz gyrotron oscillators that are used in international thermonuclear fusion devices are reviewed in detail. Some remaining critical technical problems are discussed and some technical ways that may solve the problems are also presented.%回旋管是一种具有重要发展前景的高功率毫米波和太赫兹源.本文简要介绍了回旋振荡管的结构和基本原理,并且评述了国际热核聚变装置中所用110,140和170 GHz回旋振荡管的发展现况和趋势.同时指出了回旋振荡管发展中存在的关键问题并给出了可能解决的技术途径.
