Position Reconstruction in the DEAP-3600 Dark Matter Search Experiment
The DEAP Collaboration, P. Adhikari, R. Ajaj +162
In the DEAP-3600 dark matter search experiment, precise reconstruction of the positions of scattering events in liquid argon is key for background rejection and defining a fiducial…
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 measuring systems of the wire tension for the MEG II Drift Chamber by means of the resonant frequency technique
A. M. Baldini, H. Benmansour, G. Cavoto +24
The ultra-low mass cylindrical drift chamber designed for the MEG II experiment is a challenging apparatus made of 1728 phi = 20 micron gold plated tungsten sense wires, 7680 phi =…
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…
Fluorescence of pyrene-doped polystyrene films from room temperature down to 4 K for wavelength-shifting applications
H. Benmansour, E. Ellingwood, Q. Hars +13
In liquid argon-based particle detectors, slow wavelength shifters (WLSs) could be used alongside the common, nanosecond scale, WLS tetraphenyl butadiene (TPB) for background mitig…
Development and characterization of a slow wavelength shifting coating for background rejection in liquid argon detectors
D. Gallacher, A. Leonhardt, H. Benmansour +15
We describe a technique, applicable to liquid-argon-based dark matter detectors, allowing for discrimination of alpha-decays in detector regions with incomplete light collection fr…
Pulseshape discrimination against low-energy Ar-39 beta decays in liquid argon with 4.5 tonne-years of DEAP-3600 data
The DEAP Collaboration, P. Adhikari, R. Ajaj +126
The DEAP-3600 detector searches for the scintillation signal from dark matter particles scattering on a 3.3 tonne liquid argon target. The largest background comes from Ar b…
