Position Dependent Corrections for the Electroluminescence Signal of the XENONnT Time Projection Chamber — •Peter Gyorgy — JGU Mainz

The XENONnT experiment is a dual-phase liquid xenon time projection chamber (TPC) for the direct search of Dark Matter. The electroluminescence signal (S2) is created when electrons emitted from energy deposits are extracted from the liquid into the gas phase of the TPC. Various physical effects result in a position-dependent S2 distribution, which must be corrected using calibrations. Krypton 83m provides a uniform distribution of S2 signals, which allow for the creation of a 2D correction map. This presentation discusses the S2 correction map for Science Run 1 (SR1) of XENONnT, and compares them to those of Science Run 0.
