The dark matter experiment XENONnT utilizes about 8.6 tonnes of liquid
xenon for the direct search of Weakly Interacting Massive Particles (WIMPS) and other rare event searches, employing a dual-phase Time Projection Chamber (LXe TPC).
In order to reach world-leading senstivities for the several physics channels, the target material xenon needs to be ultra-pure. Electrogentive impurities...
Direct dark matter searches require an ultra-low background, which is essential to improving sensitivity. Many efforts have been made to reduce and understand these techniques.
XENON1T observed an event excess at 1-7 keV in 2020, but not in XENONnT, which is thought to be background due to tritium. Quantitatively assessing this background is useful for future experiments.
In this talk, I...
