Abstract
The energy spectra of neutrons produced by 35 and 46 MeV protons, 16 and 28 MeV deuterons, and 44 MeV 3He ions on thick beryllium were measured at angles of 0 degrees, 15 degrees, and 45 degrees with respect to the incident beams. The spectra were measured by the time-of-flight method for neutrons from the maximum energy down to 1 MeV. Neutron dose rates obtained from the zero-degree spectra by use of available tissue kerma factors agree with TE-TE ionization chamber measurements.
摘要
在相对于入射束0度、15度和45度的角度下，测量了35和46兆电子伏质子、16和28兆电子伏氘核以及44兆电子伏氦-3离子在厚铍靶上产生的中子能谱。通过飞行时间法测量了从最大能量到1兆电子伏的中子能谱。利用现有的组织比释动能因子从零度能谱获得的中子剂量率与TE-TE电离室测量结果一致。
