Status of the DEAP-3600 experiment
  DEAP-3600 is a single-phase liquid argon (LAr) dark matter detector, located
2 km underground at SNOLAB in Sudbury, Canada, which started taking data in
2016. The detector is sensitive to nuclear recoils induced by scattering of
dark matter particles, which would cause emission of prompt scintillation
light. DEAP-3600 demonstrated excellent performance, holds the leading WIMP
exclusion among LAr detectors, and published several physics results. The WIMP
sensitivity of the detector is currently limited by backgrounds induced by
alpha activity at the LAr inlet, in a shadowed region of detector. The ongoing
hardware upgrade aims at fixing that limitation and, in consequence, at
reaching the full WIMP sensitivity. This paper summarizes the latest results
from DEAP-3600 and details of the upgrade.
