Focusing on the research direction of developing multi angle photography ability, this paper carried out the dynamic analysis and behavior research of high current electron beam deflection process. The basic problems involved in the deflection process of high current electron beam, such as the influence of space charge effect and emittance, dispersion effect and the change of beam cross-section shape, are analyzed. The achromatic deflection beam line design of a linear induction accelerator is completed by introducing a two pole magnet and a four pole magnet, so as to prevent the particles of the back sprayed target from polluting the acceleration cavity and improve the operation efficiency of the device. The 45° deflection beam line is established, the beam cluster distribution images before and after deflection are obtained, the feasibility of multi beam line operation is verified, and the key technology is accumulated for the multi angle photography operation of accelerator.
