Das EURECA Experiment

 

  • EURECA-Logo - Link to EURECA main website EURECA (European Underground Rare Event Calorimeter Array) is designed to follow on from the EDELWEISS and CRESST experiments, which have both pioneered the use of cryogenic detectors to set significant limits on WIMP dark matter using small detector masses. EURECA will consist of a single cryostat, installed in a dedicated water tank and will have two stages. The first phase will involve a cryostat and shielding with 150 kg of detectors to reach 10-10 pb sensitivity on the spin-independent WIMP-nucleon interaction cross-section while the second phase will be completed by 850 kg of additional detectors to probe 10-11 pb cross-section.
