Precision Measurement of the Specific Activity of Ar in Atmospheric Argon with the DEAP-3600 Detector
P. Adhikari, R. Ajaj, M. Alpízar-Venegas +147
The specific activity of the beta decay of Ar in atmospheric argon is measured using the DEAP-3600 detector. DEAP-3600, located 2 km underground at SNOLAB, uses a total of (…
The upgraded low-background germanium counting facility Gator for high-sensitivity -ray spectrometry
G. R. Araujo, L. Baudis, Y. Biondi +2
We describe the upgrade and performance of the high-purity germanium counting facility Gator, which is dedicated to low-background -ray spectrometry. Gator is operated at the Gr…
Ultraviolet-induced fluorescence of poly(methyl methacrylate) compared to 1,1,4,4-tetraphenyl-1,3-butadiene down to 4 K
E. Ellingwood, H. Benmansour, Q. Hars +16
Several particle-physics experiments use poly(methyl methacrylate) (a.k.a. PMMA or acrylic) vessels to contain liquid scintillators. Superluminal charged particles emitted from rad…
R&D of Wavelength-Shifting Reflectors and Characterization of the Quantum Efficiency of Tetraphenyl Butadiene and Polyethylene Naphthalate in Liquid Argon
G. R. Araujo, L. Baudis, N. McFadden +3
Detectors based on liquid argon (LAr) often require surfaces that can shift vacuum ultraviolet (VUV) light and reflect the visible shifted light. For the LAr instrumentation of the…
Temperature-dependent fluorescence emission spectra of acrylic (PMMA) and tetraphenyl butadiene (TPB) excited with UV light
J. M. Corning, G. R. Araujo, P. C. F. Di Stefano +3
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 effici…
Polyethylene naphthalate film as a wavelength shifter in liquid argon detectors
M. Kuźniak, B. Broerman, T. Pollmann +1
Liquid argon-based scintillation detectors are important for dark matter searches and neutrino physics. Argon scintillation light is in the vacuum ultraviolet region, making it har…
