Abstract

A number of proposed experiments aimed at dark matter studies are based on detection of luminescence in liquid argon at 128nm. Existing solid-state photomultipliers do not have the capability to detect emission at 128nm in the photon counting mode. Spectral properties of a new silicon photomultiplier prototype for vacuum ultraviolet registration are presented. The prototype demonstrates the photon detection efficiency about 1% in 112–182nm range.
