Description
DarkSide-20k, a noble liquid argon using double-phase time projection
chamber, being constructed as a direct dark matter detection experiment
with 50 tonnes of fiducial target mass. The key component of the
experiment is low radioactivity argon (UAr) depleted in the isotope
39Ar.
The journey of UAr shall start from Urania plant in Colorado, with a
purity of 99.99% post extraction from CO2 stream sourced from a deep
well at a rate of 250 kg/day. Next the Argon arrives at Aria plant in
Sardinia, Italy, which can perform both cryogenic and isotopic
distillation, to get a purity of 99.9999%. In order to compliment this
unique procurement chain, DArTinArDM experiment at Canfranc has been
designed to measure and monitor radiopurity of the UAr. The importance
of this supply chain and of associated techniques has gained global
attention well beyond DarkSide-20k.
