未来大视场IACT用大尺寸折射透镜原型研究
Study on a prototype of the large dimensional refractive lens for the future large field-of-view IACT
摘要：
在伽马射线天文学中，由于空间实验和地面实验之间存在差距，从100 GeV到TeV的能量范围至关重要。此外，在这个能量范围内的观测有望提供更多关于伽玛暴高能发射的细节，从而了解EBL。根据观测结果和相关知识，科学家或许能够揭开星系形成和早期宇宙演化的奥秘。下一代成像大气切伦科夫望远镜（IACT）的主要问题之一是实现更大的视场。本文报道了利用折射水凸透镜作为集光器来测试新一代IACT的可行性，并对IACT的光学特性（焦距、光斑尺寸、透过率等）进行了初步测试。介绍了0.9m直径水透镜的光电探测器和数据采集系统。
英文摘要：
In gamma ray astronomy, the energy range from sub-100GeV to TeV is crucial due to where there is a gap between space experiments and ground-based ones. In addition, observations in this energy range are expected to provide more details about the high energy emission from GRBs,and thus to understand EBL. Based on the observation results and the related knowledge, scientists may be able to unveil the mysteries of galaxy formation and the evolution of early universe. One of the principal issues for next generation Imaging Atmospheric Cherenkov Telescopes (IACT) is to achieve larger field of view (FoV). In this work, we report a refractive water convex lens as light collector to test the feasibility of a new generation of IACT, and some preliminary test results on the optical properties (the focal length, spot size, transmittance, etc.) of a 0.9 m diameter water lens, the photodetectors and DAQ system of a prototype are presented and discussed.
