论文摘要
一种用于伽马射线和带电颗粒的多理智的，基于空间的宇宙射线探测器，由于对两种颗粒的仪器要求不同，因此构成了一些设计挑战。伽玛射线检测需要用于光子转换的高Z材料层，并具有带有长杆臂的跟踪装置，以实现必要的角度分辨率以分离点源；相反，原子核的电荷测量值需要一个薄检测器，以避免不必要的碎片化和浅仪器，以使几何因素最大化。在本文中，提出了一种试图调和这两个矛盾要求的伽马射线的新颖跟踪方法。该提案基于钙化计（TIC）设计，该设计依赖于高度细分的量热量表来通过在不同深度下对电磁淋浴的横向开发进行采样。已经通过蒙特卡洛模拟研究了这种方法的有效性，并已通过检测器原型的测试梁数据进行了验证。
A multi-messenger, space-based cosmic ray detector for gamma rays and charged particles poses several design challenges due to the different instrumental requirements for the two kind of particles. Gamma-ray detection requires layers of high Z materials for photon conversion and a tracking device with a long lever arm to achieve the necessary angular resolution to separate point sources; on the contrary, charge measurements for atomic nuclei requires a thin detector in order to avoid unwanted fragmentation, and a shallow instrument so to maximize the geometric factor. In this paper, a novel tracking approach for gamma rays which tries to reconcile these two conflicting requirements is presented. The proposal is based on the Tracker-In-Calorimeter (TIC) design that relies on a highly-segmented calorimeter to track the incident gamma ray by sampling the lateral development of the electromagnetic shower at different depths. The effectiveness of this approach has been studied with Monte Carlo simulations and has been validated with test beam data of a detector prototype.
