Conductive cooling superconducting magnet system in use for gyrotron

Abstract

Through different combinations of multiple superconducting coils, superconducting magnet forms complex electromagnetic structure. Using different modes of electrical connection forms different combinations of coils. A main coil is adopted to provide central magnetic field needed. Each compensating coil is placed at two ends outside the main coil so as to generate an even magnetic field area. Multiple compensating coils with different radii and different thickness are configured at different positions along axial direction of main coil outside the main coil in order to generate more magnetic field areas, and realize magnetic fields in different compression ratios by adjusting current of compensating coil. The main coil and compensating coils are combined through cascade parallel connections so as to form multiple current lead wires connected to external power source. The invention obtains different even magnetic field areas and magnetic fields in different compression ratio.

Description

technical field [0001] The invention relates to a conduction cooling superconducting magnet system for a gyrotron, in particular to a high magnetic field superconducting magnet system for a variable magnetic field uniform region of a moving system. Background technique [0002] The gyrotron is a relativistic device with a frequency coverage ranging from centimeter waves to submillimeter waves and a huge output power. It has become one of the main devices in the fields of missile guidance, radar, electronic countermeasures and communications, and has good applications in microwave systems. prospect. High-power gyrotron devices, which can generate several megawatts of peak power or tens to hundreds of kilowatts of continuous wave power, require tens of thousands of Gauss, high uniformity and high stability special configuration strong magnetic field environment, and require magnet system Small size and movable. In a large space larger than Φ100mm, it is unrealistic or unecon...

Problems solved by technology

It brings a lot of inconvenience to the operation and movement of the superconducting magnet system. At the same time, the volume and weight of the system are large. Applying this traditional superconducting magnet cooling system in a moving system will cause difficulties in use and maintenance, as well as system damage. running unstable

[0004] Judging from the literature retrieved at home and abroad, the superconducting magnets used in microwave systems only have a single constant magnetic field uniform region, which cannot meet the needs of microwave systems to output multiple bands and different powers.
