High-dimensional Bayesian likelihood normalisation for CRESST's background model

G. Angloher, S. Banik, G. Benato, A. Bento et autres

Abstract Using CaWO4 crystals as cryogenic calorimeters, the CRESST experiment searches for nuclear recoils caused by the scattering of potential Dark Matter particles. A reliable identification of a potential signal crucially depends on an accurate background model. In this work, we introduce …

A Vibration Decoupling System for TES Operation in the COSINUS Dry Dilution Refrigerator

Moritz Kellermann, G. Angloher, M. R. Bharadawj, Mariano Cababié et autres

Abstract COSINUS will be among the first underground experiments to operate Transition Edge Sensors in a dry dilution refrigerator, measuring temperature changes on the order of $$\mu$$ μ K. A pulse tube cryocooler is used to cool down to 3K, trading simplified …

Deep-underground dark matter search with a COSINUS detector prototype

G. Angloher, I. Dafinei, N. Di Marco, L. Einfalt et autres

Sodium iodide (NaI)-based cryogenic scintillating calorimeters using quantum sensors for signal readout have shown promising first results toward a model-independent test of the annually modulating signal detected by the DAMA/LIBRA dark matter experiment. The COSINUS Collaboration has previously reported on the first …

Particle discrimination in a NaI crystal using the COSINUS remote TES design

G. Angloher, I. Dafinei, N. Di Marco, L. Einfalt et autres

The COSINUS direct dark matter experiment situated at Laboratori Nazionali del Gran Sasso in Italy is set to investigate the nature of the annually modulating signal detected by the DAMA/LIBRA experiment. COSINUS has already demonstrated that sodium iodide crystals can be operated …

Light dark matter search using a diamond cryogenic detector

G. Angloher, S. Banik, G. Benato, A. Bento et autres

Abstract Diamond operated as a cryogenic calorimeter is an excellent target for direct detection of low-mass dark matter candidates. Following the realization of the first low-threshold cryogenic detector that uses diamond as absorber for astroparticle physics applications, we now present the resulting …

Geant4 simulations of the influence of contamination and roughness of the detector surface on background spectra in CRESST

Christoph Grüner, G. Angloher, S. Banik, G. Benato et autres

CRESST is an experiment for the direct detection of dark matter, capable of detecting nuclear recoils down to 10 eV, which results in an impressive sensitivity for sub-GeV dark matter particles. For a better understanding of the measured background a background model …

Detector development for the CRESST experiment

G. Angloher, S. Banik, G. Benato, A. Bento et autres

Recently low-mass dark matter direct searches have been hindered by a low energy background, drastically reducing the physics reach of the experiments. In the CRESST-III experiment, this signal is characterised by a significant increase of events below 200 eV. As the origin …

Observation of a low energy nuclear recoil peak in the neutron calibration data of the CRESST-III experiment

G. Angloher, S. Banik, G. Benato, A. Bento et autres

New-generation direct searches for low mass dark matter feature detection thresholds at energies well below 100 eV, much lower than the energies of commonly used x-ray calibration sources. This requires new calibration sources with sub-keV energies. When searching for nuclear recoil signals, …

Quenching Factor estimation of Na recoils in NaI(Tl) crystals using a low-energy pulsed neutron beam measurement

G. Angloher, P. S. Barbeau, I. Dafinei, N. Di Marco et autres

NaI(Tl) based scintillation detectors have become a staple in the field of direct dark matter searches, with the DAMA-LIBRA experiment being the standout for its reported observation of an annually modulating WIMP-like signal which is in direct contrast with other results. In …
