DarkSide (dark matter experiment)

Darkside-10

The Darkside-10 prototype detector had 10 kg of liquid argon. It was built at Princeton University and operated there for seven months, after which it was transported to Gran Sasso National Laboratory in 2011. The detector operated in Gran Sasso 2011-2012.

Status

Darkside-50 has 46 kg argon target mass. A 3-year run is planned and ton-scale expansion has been proposed.

Initial results using a month of running were reported in 2014. Spin-independent limits were set using 1422 kg×days of exposure to atmospheric argon. A cross section limit of for a 100 Gev WIMP was found.
