GluedCaWO4 Detectors for the CRESST-II Experiment

چکیده
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 e ect of the phonons created in an attached absorber crystal. It has been observed that the scintillation of the CaWO4 absorber degrades during the process of depositing the tungsten lm. In order to prevent this, a new technique for producing the detectors was investigated. This technique might also be valuable by expanding the range of scintillator materials suitable for producing a Dark Matter detector.

Development 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 کاملThe Phase of the Annual Modulation as a Tool for Determining the WIMP Mass
The count rate of Weakly Interacting Massive Particle (WIMP) dark matter candidates in direct detection experiments experiences an annual modulation due to the Earth’s motion around the Sun. In standard isothermal halo models, the signal peaks near June 2nd at high recoil energies, but experiences a phase reversal at low recoil energies, peaking in December. We show that this phase reversal may...

متن کاملCryogenic Composite Detectors for the Dark Matter Experiments CRESST and EURECA
Weakly Interacting Massive Particles (WIMPs) are candidates for non-baryonic Dark Matter. WIMPs are supposed to interact with baryonic matter via scattering off nuclei producing a nuclear recoil with energies up to a few 10 keV with a very low interaction rate of ∼10−6 events per kg of target material and day in the energy region of interest. The Dark Matter experiment CRESST (Cryogenic Rare Ev...
متن کاملNeutron 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...
