1. How to produce the purest xenon on Earth for rare event searches with XENONnT

Dr Michael Murra (Columbia University in the City of New York)

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...

14. Tritium Background for Direct Dark Matter Search

Masaki Yamashita (Kavli IPMU, the University of Tokyo)

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...
