Temperature-dependent fluorescence emission spectra of acrylic (PMMA) and tetraphenyl butadiene (TPB) excited with UV light

Abstract

Acrylic (poly(methyl methacrylate) or PMMA) is commonly used as a vessel to hold scintillating liquids in rare-event searches. Certain types of PMMA can fluoresce with a low efficiency at room temperature. We have investigated the fluorescence spectra under 280nm ultraviolet (UV) excitation of the PMMA used in the DEAP dark matter search at various low temperatures. Fluorescence of this PMMA is observed, with an increasing intensity as the sample is cooled from a temperature of 300K down to 4K. The common wavelength-shifter tetraphenyl butadiene (TPB) is also measured for use as a reference.
