Probing spin-dependent dark matter interactions with 6 Li: CRESST Collaboration
Angloher, G.; Benato, G.; Bento, A.; Bertoldo, E.; Bertolini, A.; Breier, R.; Bucci, C.; Canonica, L.; D’Addabbo, A.; Di Lorenzo, S.; Einfalt, L.CRESST is one of the most prominent direct detection experiments for dark matter particles with sub- GeV/c2 mass. One of the advantages of the CRESST experiment is the possibility to include a large variety of nuclides in the target material used to probe dark matter interactions. In this work, we discuss in particular the interactions of dark matter particles with protons and neutrons of 6Li. This is now possi...
First measurements of remoTES cryogenic calorimeters: easy-to-fabricate particl...
Angloher, G.; Bharadwaj, M. R.; Dafinei, I.; Di Marco, N.; Einfalt, L.; Ferroni, F.; Fichtinger, S.; Filipponi, A.; Frank, T.; Friedl, M.; Fuss, A.Low-temperature calorimeters based on a readout via Transition Edge Sensors (TESs) and operated below $100$ mK are well suited for rare event searches with outstanding resolution and low thresholds. We present first experimental results from two detector prototypes using a novel design of the thermometer coupling denoted remoTES, which further extends the applicability of the TES technology by including a wider...
Cryogenic characterization of a $$\hbox {LiAlO}_{2}$$ crystal and new results o...
Abdelhameed, A. H.; Angloher, G.; Bauer, P.; Bento, A.; Bertoldo, E.; Breier, R.; Bucci, C.; Canonica, L.; D’Addabbo, A.; Di Lorenzo, S.; Erb, A.In this work, a first cryogenic characterization of a scintillating LiAlO2 single crystal is presented. The results achieved show that this material holds great potential as a target for direct dark matter search experiments. Three different detector modules obtained from one crystal grown at the Leibniz-Institut für Kristallzüchtung (IKZ) have been tested to study different properties at cryogenic temperatures...

Abdelhameed, A. H.; Angloher, G.; Bauer, P.; Bento, A.; Bertoldo, E.; Breier, R.; Bucci, C.; Canonica, L.; D'Addabbo, A.; Lorenzo, S. Di; Erb, A.The CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) dark matter search experiment aims for the detection of dark matter particles via elastic scattering off nuclei in CaWO4 crystals. To understand the CRESST electromagnetic background due to the bulk contamination in the employed materials, a model based on Monte Carlo simulations was developed using the Geant4 simulation toolkit. The res...
