Searching for Dark Matter with Cryogenic Liquids

Astronomers have found that 22% of the universe is composed of matter which does not absorb or emit light like normal matter. The DEAP-3600 & MiniCLEAN Collaborations are engaged in several experiments to search for this dark matter in the laboratory using the unique properties of liquid argon and neon.

To learn more about dark matter and the single phase experimental approach, see our About page. To learn more about DEAP-1 and DEAP-3600, see the Queen's University DEAP website.
