The DarkSide collaboration is an international affiliation of universities and labs seeking to directly detect dark matter in the form of weakly interacting massive particles (WIMPs).
The collaboration is planning, building and operating a series of liquid argon time projection chambers (TPCs) that are employed at the Gran Sasso National Laboratory in Assergi, Italy.
It was built at Princeton University and operated there for seven months, after which it was transported to Gran Sasso National Laboratory in 2011.
[3][additional citation(s) needed] Darkside-50 has 46 kg argon target mass.
[citation needed] Initial results using a month of running were reported in 2014.
