Stephen Hawking visiting the PICO Experiment

Welcome to the PICO Project


The PICO project aims to detect dark matter particles with the bubble chamber technique. PICO experiments are installed at a depth of 2 km in the SNOLAB underground laboratory in Sudbury, Ontario, Canada. The PICO collaboration is presently operating one large dark matter search experiment: a bubble chamber filled with ~57 kg of C3F8, called PICO 40L. A much larger version of the experiment with up to 500 kg of active mass is fully funded and currently in the design and procurement phase.
