Reconstruction of antineutrino interaction positions in highly segmented Solid detector

The SoLid experiment uses a highly segmented, novel detector to search for oscillations of antineutrinos produced in nuclear reactors. This paper describes an algorithm to accurately reconstruct the locations of antineutrino interactions in the detector cubes. It allows precise measurement of interaction products to estimate antineutrino energy and powerful background rejection. Three reconstruction methods are assessed, with a custom physics-based approach chosen due to superior performance.
