Search for Majorana neutrinos with the first two years of EXO-200 data
200 Collaboration, J. B. Albert, D. J. Auty +91
Many extensions of the Standard Model of particle physics suggest that neutrinos should be Majorana-type fermions, but this assumption is difficult to confirm. Observation of neutr…
Precision Measurement of the Specific Activity of Ar in Atmospheric Argon with the DEAP-3600 Detector
P. Adhikari, R. Ajaj, M. AlpÃzar-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 (…
Measurement of the scintillation time spectra and pulse-shape discrimination of low-energy beta and nuclear recoils in liquid argon with DEAP-1
P. -A. Amaudruz, M. Batygov, B. Beltran +69
The DEAP-1 low-background liquid argon detector was used to measure scintillation pulse shapes of electron and nuclear recoil events and to demonstrate the feasibility of pulse-sha…
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…
DEAP-3600 Dark Matter Search
DEAP Collaboration, P. -A. Amaudruz, M. Batygov +54
The DEAP-3600 experiment is located 2 km underground at SNOLAB, in Sudbury, Ontario. It is a single-phase detector that searches for dark matter particle interactions within a 1000…
An improved measurement of the 2νββ half-life of Xe-136 with EXO-200
J. B. Albert, M. Auger, D. J. Auty +94
We report on an improved measurement of the 2νββ half-life of Xe-136 performed by EXO-200. The use of a large and homogeneous time projection chamber allows for the precise esti…
Design and Construction of the DEAP-3600 Dark Matter Detector
P. -A. Amaudruz, M. Baldwin, M. Batygov +106
The Dark matter Experiment using Argon Pulse-shape discrimination (DEAP) has been designed for a direct detection search for particle dark matter using a single-phase liquid argon…
Search for dark matter with a 231-day exposure of liquid argon using DEAP-3600 at SNOLAB
R. Ajaj, P. -A. Amaudruz, G. R. Araujo +99
DEAP-3600 is a single-phase liquid argon (LAr) direct-detection dark matter experiment, operating 2 km underground at SNOLAB (Sudbury, Canada). The detector consists of 3279 kg of…
First results from the DEAP-3600 dark matter search with argon at SNOLAB
3600 Collaboration, P. -A. Amaudruz, M. Baldwin +102
This paper reports the first results of a direct dark matter search with the DEAP-3600 single-phase liquid argon (LAr) detector. The experiment was performed 2 km underground at SN…
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…
In-situ characterization of the Hamamatsu R5912-HQE photomultiplier tubes used in the DEAP-3600 experiment
DEAP Collaboration, P. -A. Amaudruz, M. Batygov +99
The Hamamatsu R5912-HQE photomultiplier-tube (PMT) is a novel high-quantum efficiency PMT. It is currently used in the DEAP-3600 dark matter detector and is of significant interest…
