本文描述了一个用于中能(20—100MeV/u)重离子核反应研究的高质量分辨带电粒子望远镜探测器。该望远镜由三片全耗尽硅半导体△E探测器(130μm+1580μm+5000μm)和一块10×10×30mm~3CsI(T1)闪烁体(光二极管读出)E探测器组成,具有高能量分辨、高质量分辨(对~(12)C△A/A=2.5%FWHM)、大能量范围(对于α粒子为16—350MeV)等特点,能较好地用于中能核反应研究中类弹碎片和轻粒子的同位素鉴别与能量测量。
This paper describes a high quality resolved charged particle telescope detector for the study of medium energy (20-100 MeV / u) heavy ion nuclear reactions. The telescope consists of three fully depleted silicon semiconductor ΔE detectors (130μm + 1580μm + 5000μm) and a 10 × 10 × 30mm ~ 3CsI (T1) scintillator (photodiode readout) E detector with high energy resolution , High resolution (~ 12 C △ A / A = 2.5% FWHM) and large energy range (16-350 MeV for α particle), which can be well used in the study of class bombardment And Light Particle Identification and Energy Measurement.
