Problems solved by technology

At present, the second harmonic gyrotron technology is mature, and superconducting magnets are often used to supply magnetism to its resonant cavity. However, due to the problems of low temperature maintenance and slow start-up speed of superconducting magnets, the practicability is poor.
However, if a conventional coil is used for magnetization, the power consumption is very large, and its practicality is still greatly limited.

Abstract

The invention discloses a harmonic gyrotron employing DC coil for magnetism supply, and belongs to the technical field of gyrotrons. The gyrotron comprises a magnetic control electronic gun, a resonant cavity, a quasi-optical mode converter and a collector, which are sequentially connected. The gyrotron also comprises the DC coil for supplying magnetism to a resonant cavity. The DC coil comprisesa magnet yoke part, and the magnet yoke part comprises a first magnet yoke sleeve and a second magnet yoke sleeve which are arranged on the periphery of the resonant cavity in a sleeving mode. The first magnet yoke sleeve and the second magnet yoke sleeve are arranged at an interval and fixedly connected with the resonant cavity. The direction of a magnetic line loop, outside the magnet yoke part,of the DC coil is from the first magnet yoke sleeve to the second magnet yoke sleeve. According to the invention, a superconducting magnet in the traditional harmonic gyrotron is replaced by the DC coil; meanwhile, thereby improving the start sped of the gyrotron. Meanwhile, the magnet yoke sleeves are arranged on the periphery of the resonant cavity of the gyrotron in a sleeving mode, the magnetic field generated by the DC coil is restrained and concentrated in the resonant cavity, the invalid field magnetic space is reduced, the magnetic supply efficiency of the DC coil is improved, and thepower consumption of the DC coil is reduced.

Description

technical field [0001] The invention relates to the technical field of gyrotrons, in particular to harmonic gyrotrons supplied by DC coils. Background technique [0002] The gyrotron is a fast-wave device based on the electron cyclomaser (ECM) mechanism, which can generate high-power millimeter waves, submillimeter waves and even terahertz waves, filling the gap of traditional microwave tubes and lasers in this wave band. Plasma heating, new material manufacturing, nuclear magnetic resonance and high-energy particle accelerators have broad application prospects. [0003] Among them, the cyclotron beam interacts with the high-frequency magnetic field to generate beam waves in the resonant cavity, and converts part of the energy into electromagnetic wave energy. However, since the resonant magnetic field of the gyrotron is proportional to the frequency, in the millimeter wave band, the requirement for the magnetic field is often as high as several T, which greatly limits its ...
