伽马射线能量跟踪阵列构成了高分辨率射线光谱学的技术前沿，彻底改变了现代核物理研究。其工作原理在于精确重建探测器体积内的三维射线相互作用位置。在真实的时间内获得这些相互作用点的最常用方法是将实验信号与可靠的信号库（信号基础）进行比较，该信号库将探测器响应映射为射线相互作用位置的函数。然而，获得高保真的信号基础仍然是一个巨大的技术挑战，这阻碍了这些最先进的阵列的最佳操作。在这篇文章中，我们提出了一个开创性的和非常简单的方法，实验产生一个可靠的信号基础。所提出的方法使射线跟踪设备，以执行其位置敏感响应的自校准原位，开辟了第一次达到其最佳性能的方式。
Gamma-ray energy tracking arrays constitute the technological frontier of high-resolution-ray spectroscopy revolutionizing modern nuclear physics investigations. Their principle of operation lies on the precise reconstruction of the three-dimensional-ray interaction positions within the detector volume. The most common method to obtain these interaction points in real time is to compare the experimental signals against a reliable library of signals (signal basis) that maps the detector response as a function of the-ray interaction position. Obtaining a high-fidelity signal basis, however, remains a big technological challenge, which hinders the optimal operation of these state-of-the-art arrays. In this article, we propose a pioneering and notably simple method for generating experimentally a reliable signal basis. The proposed method enables the-ray tracking devices to perform a self-calibration of their position sensitive responsein situ, opening up the way for reaching their optimum performance for the first time.
