EURECA: towards high sensitivity in the low-mass WIMP region — •Valentin Kozlov for the EURECA collaboration — Karlsruher Institut für Technologie, Institut für Kernphysik, Postfach 3640, 76021 Karlsruhe
The EURECA project is aimed at direct search for dark matter particles using cryogenic bolometers. It is primarily based on the expertise of the EDELWEISS and CRESST experiments, but also a close collaboration with the U.S.-led experiment SuperCDMS is foreseen. Thus in the first instance EURECA will host germanium and CaWO4 crystals with the goal to significantly improve sensitivity on the WIMP-nucleon elastic scattering cross-section, especially in the low-mass WIMP region to go down to the neutrino floor. This requires to overcome many challenges. Ongoing R&D work concerning detectors, electronics read-out, material screening, and technical developments towards common detector infrastructure will be presented.
