回旋管是问世不久的新型微波电子管。它的工作原理是依靠高速电子在磁场中回旋振荡把直流电能转变成微波能的。由此决定了这种管子必须有良好的磁系统。磁场强度随工作频率增加而增加。对于厘米波段的管子采用常温电磁线包系统,可以达到所要求的磁场值,而对更短波长的管子则必须用超导磁体。我们研制的超导磁体使用于3毫米回旋管。本课题的主要技术要求: 1 杜瓦室温孔直径为60mm,室温孔的杜瓦芯柱直径为φ110mm; 2 磁场要求: (1) 中心磁场强度为36000高斯,在40mm范围内均匀; (2) 在阴极端,距强磁场中心为190
Gyrotron is a new microwave tube that came out soon. Its working principle is to rely on high-speed electrons in the magnetic field gyration oscillation DC power into microwave energy. This determines the tube must have a good magnetic system. Magnetic field strength increases with increasing operating frequency. For centimeter-band tubes using a normal temperature wire package system, you can achieve the required magnetic field values, and for shorter wavelength tubes you must use superconducting magnets. We developed a superconducting magnet for use in a 3 mm gyrotron. The main technical requirements of the subject: 1 Dewar room temperature hole diameter of 60mm, room temperature hole Duval core diameter of φ110mm; 2 magnetic field requirements: (1) the center of the magnetic field strength of 36000 Gauss, uniform within the range of 40mm; (2) At the cathode, the distance from the strong magnetic field is 190
