2000年气球飞行活动中LXeGRIT对MeV γ射线探测效率的研究
A Study of the LXeGRIT Detection Efficiency for MeV Gamma-Rays during the 2000 Balloon Flight Campaign
摘要：
LXeGRIT --液体氙伽马射线成像望远镜--是用于\MeV \g射线天体物理学的康普顿望远镜的第一个原型，该望远镜基于LXeGRIT时间投影室。康普顿望远镜的最相关的品质因数之一是探测效率为\g -射线，这取决于不同的贡献，如探测器的几何形状和被动材料，触发效率，死时间等的LXeGRIT仪器的效率的详细研究，实验室测量和蒙特卡罗模拟的基础上，本文提出。
英文摘要：
LXeGRIT - Liquid Xenon Gamma-Ray Imaging Telescope - is the first prototype of a Compton telescope for \MeV \g-ray astrophysics based on a LXe time projection chamber. One of the most relevant figures of merit for a Compton telescope is the detection efficiency for \g-rays, which depends on diverse contributions such as detector geometry and passive materials, trigger efficiency, dead time, etc. A detailed study of the efficiency of the LXeGRIT instrument, based both on laboratory measurements and Monte Carlo simulations, is presented in this paper.
