新型望远镜带电粒子探测系统结构设计与理论模拟
Constructional Design and Theoretical Simulation of Novel Telescope System for Charged Particle Detection
摘要
Abstract
In order to study the reaction mechanism of exotic nuclei far from β stability line based on complete kinematic measurement on the Radioactive Ion Beam Line in Lanzhou (RIBLL1) at the Heavy‐Ion Research Facility in Lanzhou (HIRFL) ,a charged particle detector array ,which is composed of multiple identical telescope systems ,is needed to be developed .Each telescope ,a full function detector module ,consists of a double‐side silicon strip‐detector (16 × 16 ) with thickness of 65 μm , a pixel‐silicon detector with 16 (4 × 4) pixels with thickness of 1 000μm ,and an array of 4 × 4 CsI(Tl) crystals with length of 5 cm which are read out by avalanche photo diodes (APD) .The detector array has performance characteristics of high energy resolution over a wide dynamic range in energy ,reasonable position resolution and large solid‐angle coverage . It also can detect multiple particles simultaneously .In this work ,a detailed simulation of the detector module was performed based on Geant4 .With the simulation and the experimental tests of each part of the detector module ,the design construction and a whole predicting performance of the detector module were given .关键词
