5×5阵列PHOSWICH闪烁探测器望远镜

A 5×5 Phoswich telescope detectors array

描述了一个 5× 5阵列带电粒子 PHOSWICH闪烁探测器望远镜结构。它的每一个单元由 1片厚度为 1mm,面积为 2 4 mm× 2 4 mm快塑料闪烁体 NE10 2 A和 1个前表面为 2 4 mm× 2 4 mm,后表面为 37mm×37mm,厚度为 4 0 mm的 Cs I( Tl)晶体组成的。在兰州放射性离子次级束流线 ( RIBL L )上测试到 Z/ΔZ =2

This paper describes a 5×5 Phoswich telescope detectors array . In each unit, it consists of a fast plastic scintillator, which is 24×24mm 2 in area and 1mm in thickness, and a CsI(Tl) crystal, whose front surface is same as the fast plastic scintillator in area, and its back surface is 37×37 mm 2 in area, with 40 mm in thickness. The array's mechanism and performances are introduced here. And the array's experimental results in RIBLL (Radioactive Ion Beam Line in Lanzhou) are used to describe its performance.
