The Liquid Argon Purity Demonstrator was an R&D test stand designed to determine if electron drift lifetimes adequate for large neutrino detectors could be achieved without first evacuating the cryostat. We describe here cryogenic system, its operations, and apparatus used contaminant levels in argon measure lifetime. liquid purity obtained by this system facilitated a gaseous purge. Additionally, impurities from ullage were prevented entering at gas-liquid interface condensing gas filtering...

Abstract The Muon g -2 Experiment at Fermilab uses a gaseous straw tracking detector to make detailed measurements of the stored muon beam profile, which are essential for experiment achieve its uncertainty goals. Positrons from decays spiral inward and pass through before striking an electromagnetic calorimeter. is therefore located inside vacuum chamber in region where magnetic field large non-uniform. As such, must have low leak rate maintain high-quality vacuum, be non-magnetic so as not...
