论文摘要
电子峰值对产生是高能伽马射线天体物理观察的重要过程。在开创性的OSO-3反向望远镜之后，该场演变为使用粒子跟踪仪器，主要源自高能物理探测器。尽管许多技术是在气球传播的伽马射线望远镜上开发的，但逃脱大气中高背景的需求意味着突破性发现来自SAS-2和COS-B卫星。下一个主要的配对生产成功是在康普顿伽玛射线天文台上的乌鸦，该天文台在100 meV以上的能源上提供了第一张全天空地图，并发现了各种伽马射线源，其中许多是可变的。当前一代的配对望远镜（敏捷和费米LAT）扩大了高能量伽马射线天体物理学，特别强调了多波长和多通用器研究。基于配对生产以及改进的乐器性能，以后的任务仍然有多种选择。
Electron-positron pair production is the essential process for high-energy gamma-ray astrophysical observations. Following the pioneering OSO-3 counter telescope, the field evolved into use of particle tracking instruments, largely derived from high-energy physics detectors. Although many of the techniques were developed on balloon-borne gamma-ray telescopes, the need to escape the high background in the atmosphere meant that the breakthrough discoveries came from the SAS-2 and COS-B satellites. The next major pair production success was EGRET on the Compton Gamma Ray Observatory, which provided the first all-sky map at energies above 100 MeV and found a variety of gamma-ray sources, many of which were variable. The current generation of pair production telescopes, AGILE and Fermi LAT, have broadened high-energy gamma-ray astrophysics with particular emphasis on multiwavelength and multimessenger studies. A variety of options remain open for future missions based on pair production with improved instrumental performance.
