Problems solved by technology
[0003] Existing magnetic field measuring devices are bulky and can only measure the magnetic field in one direction, and cannot make the magnetic field measuring device coincide precisely with the center of the magnetic field
In addition, due to the ferromagnetism of the motor, the magnetic field is affected, especially when the magnetic field strength is large, the motor cannot even work normally under the interference of the magnetic field, making it very difficult to measure the magnetic field

Description
technical field [0001] The invention belongs to the technical field of magnetic field measurement, and more particularly relates to a device for measuring the magnetic field distribution of a superconducting magnet. Background technique [0002] After entering the 21st century, the research and development of controlled thermonuclear fusion are closely related to the world energy crisis, and the auxiliary heating method of controlled thermonuclear fusion is mainly Electron Cyclotron Resonance Heating (ECRH), in which superconducting magnets are The core component of the ECRH system. In the ECRH system, in order to make the system work normally, in addition to providing a stable high-voltage power supply, a superconducting magnet is also required to provide a specific magnetic field distribution. Therefore, in order to ensure the normal operation of the gyrotron at a specific and stable frequency, it is necessary to accurately measure the magnetic field of the superconductin...
