近年来,高能重离子反冲法(H■ERDA)在分析材料表层轻元素剖面分布方面越来越显示出它的优越性。特别是在加上粒子分辨技术以后,已成了一个独一无二的能非破坏性地同时分析多个轻元素剖面分布的近表层分析技术。为了在我院串列加速器上发展这种技术和探索高灵敏测氢技术,我们设计制作了一个结构简单,体积小巧的纵向场无栅气-固式△E-E粒子分辨望远镜。望远镜的△E探测器是一个纵向场电离室,E探测器 In recent years, the high-energy heavy ion recoil method (H ERDA) has shown its superiority in analyzing the profile of light elements in the surface of materials. In particular, with the addition of particle resolution, it has become a unique near-surface analysis technique that can simultaneously and non-destructively analyze the distribution of multiple light element profiles. In order to develop this technology and explore the highly sensitive hydrogen detection technology in the tandem accelerator of our institute, we designed and manufactured a longitudinal field Grating-E-E Particle Separation Telescope with simple structure and compact size. The telescope’s ΔE detector is a longitudinal field ionization chamber, E-detector
