用于核伽马射线天体物理学（类似于0.2 - 20 MeV）的锗康普顿望远镜的开发需要新的事件重建技术，以准确确定光子事件的初始方向和能量，以及一致地拒绝背景事件。本文介绍了事件重建技术，占现实的仪器/探测器的性能和不确定性。一个特别重要的技术是康普顿运动学识别，它允许适当的相互作用排序和背景拒绝与高概率。这些技术的使用对于实际评价任何锗康普顿望远镜配置的性能和灵敏度至关重要。
The development of germanium Compton telescopes for nuclear gamma-ray astrophysics (similar to 0.2 - 20 MeV) requires new event reconstruction techniques to accurately determine the initial direction and energy of photon events, as well as to consistently reject background events. This paper describes techniques for event reconstruction, accounting for realistic instrument/detector performance and uncertainties. An especially important technique is Compton Kinematic Discrimination, which allows proper interaction ordering and background rejection with high probabilities. The use of those techniques are crucial for the realistic evaluation of the performance and sensitivity of any germanium Compton telescope configuration.
