Dark matter remains one of the greatest puzzles of the 21st century, with the quest to understand, interpret and discover this elusive particle captivating the scientific community for close to 50 years. The study of dark matter is not only fascinating from a scientific perspective but also has profound implications for our understanding of the universe. Join us on this exciting journey of discovery as we aim to shed new light on some long-standing questions while testing out new and promising detector designs!


What we do

Extensive R&D is essential for the development of detectors, front-end electronics and a robust data-analysis pipeline, all of which is complemented with a state-of-the-art underground cryogenic facility.


A new detector readout design dubbed “remoTES” has been successfully demonstrated, allowing for the operation of NaI crystals at milli kelvin temperatures for the first time.
