Jingxiu Li, Ying Yao, Aoling Guo, et al. Measurement of electron beam energy spectrum for electron linac[J]. Nuclear techniques, 1990, 13(4): 224-227.DOI:
A magnetic analyzer and a plastic scintillation detector were used to measure electron beam energy spectrum of the 30 MeV electron linac. It was found that the energy spread of the electron beam was nearly 15%.
