Signal corrections with the XENONnT analysis framework — •Johanna Jakob for the XENON collaboration — Institut für Kernphysik, WWU Münster

The upcoming dark matter experiment XENONnT is currently under construction at Laboratori Nazionali del Gran Sasso (LNGS). The detector uses a dual-phase time projection chamber (TPC) filled with liquid and gaseous xenon to detect scattering of WIMPS. The TPC design allows to perform 3D position reconstruction of the recorded events. The XENONnT TPC is designed in a way that most of the XENON1T infrastructure can be reused, featuring a maximized active detector volume. XENONnT has a novel, faster analysis framework called strax(en) which has to be verified with data from the XENON1T experiment.

The talk will focus on using the new XENONnT data analysis framework with calibration data already used for the dark matter search with the XENON1T experiment. Light Collection Efficiency (LCE) maps, used to compensate the position-dependent light yield, are extracted and compared to the former data processor (PAX).
