The LUX-ZEPLIN (LZ) radioactivity and cleanliness control programs
Akerib, D. S.; Akerlof, C. W.; Akimov, D. Yu.; Alquahtani, A.; Alsum, S. K.; Anderson, T. J.; Angelides, N.; Araújo, H. M.; Arbuckle, A.LUX-ZEPLIN (LZ) is a second-generation direct dark matter experiment with spin-independent WIMPnucleon scattering sensitivity above 1.4 × 10−48 cm2 for a WIMP mass of 40 GeV/c2 and a 1000 days exposure. LZ achieves this sensitivity through a combination of a large 5.6 t fiducial volume, active inner and outer veto systems, and radio-pure construction using materials with inherently low radioactivity content. Th...
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...
New limits on the resonant absorption of solar axions obtained with a $$^\mathb...
Abdelhameed, A. H.; Bakhlanov, S. V.; Bauer, P.; Bento, A.; Bertoldo, E.; Canonica, L.; Derbin, A. V.; Drachnev, I. S.; Iachellini, N. FerreiroA search for resonant absorption of solar axions by 169Tm nuclei was carried out. A newly developed approach involving low-background cryogenic bolometer based on Tm3Al5O12 crystal was used that allowed for significant improvement of sensitivity in comparison with previous 169Tm based experiments. Themeasurements performed with 8.18 g crystal during 6.6 days exposure yielded the following limits on axion coupli...

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...
