The beam calibration loop model device of high energy detector provides the simulated thermal vacuum environment for the beam target station of the experimental station on the ground, which is the main equipment of the electron beam line device experimental station of accelerator. The device is the first accelerator beam line device in China that can provide pulse mode quasi single electron beam. It can provide electromagnetic shielding environment, high and low temperature cold black background, clean and pollution-free high vacuum environment for sample beam test, and can be used for electronic calibration test of various space particle detectors.
