The Deep Underground Neutrino Experiment is advancing technology commonly used in dark matter experiments—and scaling it up to record-breaking sizes.

From FAPESP’s Pesquisa, March 2018: International researchers are constantly looking for lighter particles in the hope of finding dark matter, including at the DarkSide-50 experiment, CDMS and the Dark Energy Survey.

The DarkSide time projection chamber was installed in its cryostat and then lowered into the center of a 4-meter-diameter metal sphere, which will be filled with liquid scintillator. The liquid scintillator is used to identify neutrons, which are a background to the dark-matter search.
