Design and construction of the DEAP-3600 dark matter detector

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 target. The projected cross section sensitivity for DEAP-3600 to the spin-independent scattering of Weakly Interacting Massive Particles (WIMPs) on nucleons is 10^–46cm² for a 100 GeV/c² WIMP mass with a fiducial exposure of 3 tonne-years. In conclusion, this paper describes the physical properties and construction of the DEAP-3600 detector.. Authors: Amaudruz, P. -A.; Baldwin, M.; Batygov, M.; Beltran, B.; Bina, C. E..
