DEAP-3600 entered its cooldown phase—a gradual descent to cryogenic temperatures (-186°C) needed to operate with liquid Ar, the heart of the experiment. A weeks-long process ensures every component adjusts safely, preparing the detector to hunt for elusive #darkmatter. A new chapter in our mission❄️
