Neutron Background Studies for the CRESST Dark Matter Experiment
The new detection concept applied for the direct WIMP search experiment CRESST II, which enables a clear discrimination between electron recoils and nuclear recoils, will leave neutrons as the main background. This background will soon limit the sensitivity of the experiment and therefore become an important issue for the next phase of CRESST. We have performed a study based on Monte Carlo simu...
متن کاملDevelopment of cryogenic phonon detectors based on CaMoO4 and ZnWO4 scintillating crystals for direct dark matter search experiments
This work reports on the development of the first phonon detectors based on CaMoO4 and ZnWO4 scintillating crystals for the CRESST-II experiment. In particular, a novel technique for the production of the ZnWO4 phonon detector with a separate thermometer carrier was investigated. The influence of the thermal and mechanical treatment on the scintillation light output of CaMoO4 and ZnWO4 crystals...
متن کاملGluedCaWO4 Detectors for the CRESST-II Experiment
The Cryogenic Rare Event Search with Superconducting Thermometers Phase II (CRESST-II) at the L.N.G.S in Italy is searching for Dark Matter using low-temperature calorimeters. These detectors allow to discriminate di erent particles by simultaneous measurement of phonons and scintillation light. The sensors used consist of superconducting tungsten thinlm thermometers, which measure the thermal ...
متن کاملLight Dark Matter in the light of CRESST-II
Recently the CRESST collaboration has published the long anticipated results of their direct Dark Matter (DM) detection experiment with a CaWO4 target. The number of observed events exceeds known backgrounds at more than 4σ significance, and this excess could potentially be due to DM scattering. We confront this interpretation with null results from other direct detection experiments for a numb...
متن کاملEnergy-dependent light quenching in CaWO4 crystals at mK temperatures
ScintillatingCaWO4 single crystals are a promising multi-element target for rare-event searches and are currently used in the direct dark matter experiment CRESST (Cryogenic Rare Event Search with Superconducting Thermometers). The relative light output of different particle interactions in CaWO4 is quantified by quenching factors (QFs). These are essential for an active background discriminati...
متن کاملLimits on Momentum-Dependent Asymmetric Dark Matter with CRESST-II.
The usual assumption in direct dark matter searches is to consider only the spin-dependent or spin-independent scattering of dark matter particles. However, especially in models with light dark matter particles O(GeV/c^{2}), operators which carry additional powers of the momentum transfer q^{2} can become dominant. One such model based on asymmetric dark matter has been invoked to overcome disc...
