The DEAP-3600 experiment is searching for Dark Matter with a 3600 kg single phase liquid argon (LAr) target and a projected exclusion sensitivity to the spin-independent 100 GeV WIMP-nucleon cross-section of 10$^{-46}$ cm$^{2}$ after a background-free exposure of 3000 kg$\cdot$yr.
The experimental signature are keV-scale WIMP recoils producing 128 nm LAr scintillation photons which are...
Experiments currently searching for dark matter, studying properties of neutrinos or searching for neutrinoless double-beta decay require very low levels of radioactive backgrounds both in their own construction materials and in the surrounding environment. These low background levels are required so that the current and next generation experiments can achieve the required sensitivities for...
DEAP-3600 is a liquid argon experiment for direct dark matter detection which is located $2$km underground at the SNOLAB facility in Lively, Ontario. It was designed with a target sensitivity of $10^{-46}$cm$^2$ for the spin-independent scattering cross section of Weakly Interacting Massive Particles (WIMPs) at masses of $100$GeV on the nucleons of the scintillation material. Nuclear recoils...
Protection from and rejection of backgrounds are key issues for direct dark matter detection experiments.
The next-generation SuperCDMS SNOLAB experiment will be described, focusing on background strategy and characterization.
The potential of SuperCDMS detectors for achieving very low energy threshold is particularly attractive for searches for WIMPs with masses below 10 GeV/c^2.
Thus, the...
