First, the question put forward: Beijing Electron Positron Collider spectrometer magnet, the detector is the main body of the machine. Magnetic fields are provided to the detector. In future physics experiments, the magnetic field parameters are a basic data when analyzing the characteristic parameters of the particles. Therefore, the accuracy of the magnetic field of the spectrometer magnet directly affects the result of the physical experiment. At the same time as the positive and negative electron collision point in the spectrometer magnet, the distribution of the magnetic field also directly affect the collision position adjustment. Therefore, the parameters of the magnet in the collider engineering implementation process is also a very important parameter. In order to obtain the important parameters of the magnetic field, it must be magnetic spectrometer
