The Effects of Dissolved Methane upon Liquid Argon Scintillation Light [PDF]

, 2013
In this paper we report on measurements of the effects of dissolved methane upon argon scintillation light. We monitor the light yield from an alpha source held 20 cm from a cryogenic photomultiplier tube (PMT) assembly as methane is injected into a high-
