Matrix formalism and singular-value decomposition for the location of gamma interactions in segmented HPGe detectors
摘要：
现代同轴和平面HPGe探测器可以精确确定撞击伽马射线的能量和轨迹。这需要根据传递信号的形状确定晶体内部伽马相互作用的位置。本文回顾了HPGe响应函数的分析的艺术状态，并提出了导致最佳信号分解的方法。通用矩阵方法允许快速定位的相互作用，即使当诱导的信号强烈重叠。
英文摘要：
Modern coaxial and planar HPGe detectors allow a precise determination of the energies and trajectories of the impinging gamma-rays. This entails the location of the gamma interactions inside the crystal from the shape of the delivered signals. This paper reviews the state of the art of the analysis of the HPGe response function and proposes methods that lead to optimum signal decomposition. The generic matrix method allows fast location of the interactions even when the induced signals strongly overlap.
