Flow and thermal modelling of the argon volume in the DarkSide-20k TPC
20k Collaboration, F. Acerbi, P. Adhikari +300
The DarkSide-20k dark matter experiment, currently under construction at LNGS, features a dual-phase time projection chamber (TPC) with a ~50 t argon target from an underground wel…
Direct Measurement of the Ar Half-life from 3.4 Years of Data with the DEAP-3600 Detector
DEAP Collaboration, P. Adhikari, R. Ajaj +114
The half-life of Ar is measured using the DEAP-3600 detector located 2 km underground at SNOLAB. Between 2016 and 2020, DEAP-3600 used a target mass of (3269 24) kg of…
DarkSide-20k sensitivity to light dark matter particles
20k Collaboration, F. Acerbi, P. Adhikari +310
The dual-phase liquid argon time projection chamber is presently one of the leading technologies to search for dark matter particles with masses below 10 GeV/c. This was demons…
Benchmarking the design of the cryogenics system for the underground argon in DarkSide-20k
20k Collaboration, F. Acerbi, P. Adhikari +315
DarkSide-20k (DS-20k) is a dark matter detection experiment under construction at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. It utilises ~100 t of low radioactivity a…
