Abstract：
This paper gives the motion of electrons in the alpha magnet firstly,then represents the physical design of an alpha magnet used in Beijing Free Electron Laser.The measured distribution of field gradient of the alpha magnet is reported.The field region with well distribution of │ΔG/G│<1.5% is from 0 to 13.3cm.The simulation and beam test proved that this magnet meets the requirement of the microwave electron gun.
