Abstract
MiniCLEAN is a single-phase liquid argon dark matter experiment. During the initial cooling phase, impurities within the cold gas (< 140 K) were monitored by measuring the scintillation light triplet lifetime, and ultimately a triplet lifetime of 3. 480 ± 0. 001 (stat.) ± 0. 064 (sys.) μs was obtained, indicating ultra-pure argon. This is the longest argon triplet time constant ever reported. The effect of quenching of separate components of the scintillation light is also investigated.
