本文介绍制作的一台用于重离子鉴别的Bragg曲线谱仪。它是一种电场平行于入射粒子方向的全阻止型电离室。其性能用ThC-C’α源和~(252)Cf源进行了测试。对8.785MeV α粒子(ThC’源)能量分辨好于1％,电荷分辨Z/ΔZ=50。
This article describes the production of a Bragg curve spectrometer for heavy ion identification. It is a fully impeded ionization chamber with an electric field parallel to the incident particle. Its performance was tested with ThC-C’α source and ~ (252) Cf source. The energy resolution for the 8.785 MeV alpha particle (ThC ’source) is better than 1% and the charge resolution Z / ΔZ = 50.
