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 response in situ, opening up the way for reaching their optimum performance for the first time.
