The cresst dark matter search
Proceedings of the 6th International Workshop on the Identification of Dark Matter, IDM 2006 (2007) 192-197
Abstract:
CRESST I1 is a WIMP search experiment using cryogenic detectors to detect heat and scintillation signals in Caw04 crystals simultaneously. Competitive limits on the coherent WIMP-nucleon scattering cross section and other results from runs from the upgrade to CRESST I1 are shown. New features and upgrades installed on the CRESST I1 setup are described and the status of the experiment is presented.CRESST - status and future
NUCL PHYS B-PROC SUP 173 (2007) 104-107
Abstract:
We present results on WIMP dark matter interaction, obtained using cryogenic phonon-scintillation detectors. The targets are CaWO4 scintillating crystals with phonon sensors, while scintillation is detected with an associated cryogenic light detector. The combination of phonon and light signals leads to a strong suppression of nonnuclear recoil backgrounds. Results obtained before the upgrade of CRESST are presented and a status report on the upgrade itself is given.EURECA - the European future of dark matter searches with cryogenic detectors
NUCL PHYS B-PROC SUP 173 (2007) 168-171
Abstract:
EURECA (European Underground Rare Event Calorimeter Array) is a new project, searching for dark matter, with largely the present groups of the CRESST and EDELWEISS experiments and already a few new groups. The aim is to explore scalar cross sections in the 10(-9) - 10(-10) picobarn region with a target mass of up to one tonne. A major advantage of EURECA is our planned use of more that just one target material (multi target experiment for WIMP identification). In preparation for this large-scale experiment, R&D for EURECA is provided through the current phases of CRESST and EDELWEISS.Development of superconducting contacts for the CRESST II 66-channel superconducting quantum interference device readout system.
Rev Sci Instrum 78:7 (2007) 073301
Abstract:
The CRESST experiment is designed to search for weakly interacting massive particle dark matter with cryogenic detectors. CRESST II will use up to 33 CaWO(4) crystals with a total mass of approximately 10 kg. These many detectors require a readout system based on 66-channel superconducting quantum interference devices (SQUIDs). In this article we report on the development of a modular superconducting connector for the 66-channel SQUID readout circuit. We show that the technique developed reliably produces superconducting contacts.Scintillation studies of CaWO4 in the milli-kelvin temperature range
