高频高压电子辐照加速器主机室辐射场研究

Abstract

Abstract: By using MCNP simulation and measurement, the source terms and the influence factors to its field strength was researched for the machine hall of high frequency and high voltage electron irradiation
accelerator. The results show that the source terms in machine hall mainly come from the scattering irradiation after electrons shooting the target in radiation room. The radiation field intensity in the machine hall is determined by the sizes of the pipe hole between the machine hall and radiation room, and the thicknesses of shielding material in the pipe hole.

Key words: high frequency and high voltage electron irradiation accelerator, machine hall, MCNP, source term
