AbstractThis paper reports our progress of developing a 0.33-THz gyrotron which is based on a compact pulse magnet and can generate broadband coherent THz radiation with bandwidth exceeding 10 GHz and peak power about 2 kW. The design and fabrication of the key components are addressed in detail, including strong-field magnet, pre-bunched cavity, broadband Quasi-Optical mode converter, and Brewster window.

 摘要:本文介绍了小型化的太赫兹宽带脉冲回旋管的设计与研制。系统采用开放式谐振腔TE62模式回旋基波工作,集成了电子枪、脉冲磁体、宽带互作用电路、准光模式转换器及宽带布鲁斯特窗。脉冲磁体可极大降低系统体积,使得整管尺寸小到25 cm × 25 cm × 42 cm。预群聚腔互作用电路可有效扩展返波工作带宽,在0.328 THz - 0.338 THz的频带内产生宽带太赫兹波,功率约1 kW - 2.5 kW。本文的研究对探索新型高功率太赫兹应用具有重要意义。
