太赫兹真空源斜注管高频结构研究

Analysis of Vacuum THz Source Clinotron Slow-Wave Structure

斜注管的工作原理是将电子注稍微倾斜于慢波系统表面,通过改变电子注的倾角,来优化有效互作用长度,实现较高的输出功率和效率,可以作为一种新型高功率太赫兹器件。本文就国外的发展情况进行了评述。初步设计了W波段斜注管的几何尺寸和电尺寸,并对其"冷"特性进行了初步研究。

The working principle of the clinotron is slightly tilting the electron beam to the surface of the slow-wave system,optimizing the length of the effective interaction by varying the angle of the electron beam to obtain high output power and efficiency.The clinotron can be used as a new type of high power THz device.The development of the clinotron in foreign countries was reviewed in this paper.Moreover,we preliminary designed the physical dimension and the electrical size of the W-band clinotron,and also investigated its'cold'characteristic.
