Particle detectors utilising liquid targets have been successfully used since the 1950s for a wide range of physics applications. These liquid detectors have been instrumental in numerous groundbreaking physics searches and discoveries, and remain among widely used in particle and nuclear experiments. Modern liquid detectors normally employ target media of water, liquid scintillator, or cryogenic noble liquids Current physics applications of liquid detectors are in the domain of rare event searches across all of astroparticle physics, including fundamental open questions in neutrino and dark matter physics. Development of liquid detectors at all stages ranging from development and characterisation to purification and deployment has been identified as one of the key technology domains required for the next generation detectors.

The DRD2 Collaboration was formed in 2023 to organise the international community towards tackling these critical upcoming challenges. The primary objective of the DRD2 collaboration is to develop liquid technologies which are needed for next generation detectors, fostering collaboration with industry, and creating international cross-fertilization among institutes and research fields.
