Description
DarkSide-50 (DS-50) at Gran Sasso underground laboratory, Italy, is a
direct dark matter search experiment based on a TPC with liquid argon
from underground sources. The DS-50 TPC, with 50 kg of active argon
and a fiducial mass of ~37 kg, is installed inside an active neutron
veto based on a boron-loaded organic scintillator. The neutron veto is
built inside a water cherenkov muon veto.
DS-50 has been taking data since Nov 2013, collecting 47 days livetime
of data with atmospheric argon. Also, recently DS-50 commissioned
liquid Ar from underground and measured the level of radioactive 39Ar.
The first physics result from DarkSide as well as underground argon
performance will be presented. This is the most sensitive dark matter
search preformed with an argon target.
