Abstract
The XENON project, located at INFN Laboratori Nazionali del Gran Sasso, aims to directly detect dark matter particles, through the interaction with xenon atoms inside a dual-phase Time Projection Chamber. At the end of the last XENON1T science run, in 2018, a low-energy calibration with an internal 37Ar source was performed for the first time. 37Ar decays by electron capture, with 35-days half-life, emitting photons and electrons which generate two mono energetic signals, at 2.82keV (K-shell) and 0.27keV (L-shell). The final results of the calibration confirm that the behaviour of the detector is well-understood. Additionally, it was proven that cryogenic distillation efficiently removed 37Ar and, therefore, this source can be used for calibrations in multi-tonne xenon detectors.
