Descripción

DEAP-3600 is the largest running dark matter detector filled with liquid argon, set at SNOLAB, in Sudbury, Canada, 2 km underground. The experiment holds the most stringent exclusion limit in non-Xe target for WIMPs above 10 GeV/c$^2$.

In the published analysis the main background reducing the sensitivity were events induced by alpha particles in some surfaces and in suspended dust. I will describe the general status of the experiment, focusing on these background sources and present the status of both the hardware upgrades and the multivariate analysis developed to decrease their impact and eventually improve the detector sensitivity in the upcoming WIMP search.
