Measure electron beam energy with the time-resolved beam parameters measurement system and magnetic analyzer mode

Time-resolved beam parameters measurement system can be achieve electron beam energy in LIA. In this paper introduce work principle and method of time-resolved beam parameters measurement system. Show the experiment layout of energy measuring. The principle of magnetic analyzer was described, with the bending radius of 300 mm and the bending angle of 60 degree after hard-edge approximation, The measured energy is about 18MeV, the maximum energy variation is 2%.
