论文摘要
高级康普顿望远镜似乎是MEV系列中下一代伽马射线空间天文台的最佳仪器概念。正在开发高级康普顿望远镜的第一个原型，以匹配纳米卫星任务的约束，并具有测量伽马射线爆发及时迅速发射极化的科学目标。我们针对该项目的工具开发的重点是由单层无机CEBR制成的位置敏感量热计模块$ _3 $闪烁体由像素化的光电探测器读取。 3D位置重建是通过对每个空间方向进行优化至2 mm的不确定性的深度学习算法获得的。
An advanced Compton telescope appears to be the best instrument concept for the next generation gamma-ray space observatory in the MeV range. A first prototype of advanced Compton telescope is being developed to match the constraints of a nano satellite mission, with the scientific objective of measuring gamma-ray burst prompt emission polarization. Our instrumental developments for this project are focusing on the position-sensitive calorimeter module, made of a monolithic inorganic CeBr$_3$ scintillator read by a pixelated photodetector. 3D position reconstruction is obtained by deep-learning algorithms that have been optimized down to an uncertainty of 2 mm for each spatial direction.
