Light Dark Matter Search with 7.8 Tonne-Year of Ionization-Only Data in XENONnT
E. Aprile, J. Aalbers, K. Abe +174
We report on a blinded search for dark matter (DM) using ionization-only (S2-only) signals in XENONnT with a total exposure of over 579 days…
An LNGS Mobile Neutron Detector (ALMOND): Mapping Ambient Neutron Background of Gran Sasso National Laboratory
Melih Solmaz, Klaus Eitel, Alfredo Davide Ferella +3
In deep underground laboratories, environmental neutrons, which are produced at the cavern walls, introduce a source of background to rare event searches. The flux and spectrum of…
Commissioning of a mobile neutron spectrometer for LNGS
Francesco Pompa, Klaus Eitel, Alfredo Davide Ferella +3
Environmental neutrons are a source of background for rare event searches in underground laboratories. Since the majority of the neutron background comes from the cavern walls due…
Comparison of the detector response and calibration function of metallic microcalorimeters for X-ray photons and external electrons
Neven Kovac, Fabienne Adam, Sebastian Kempf +6
Metallic microcalorimeters (MMCs) are cryogenic single-particle detectors that rely on a calorimetric detection principle. Due to their excellent energy resolution, close-to-ideal…
DELight: a Direct search Experiment for Light dark matter with superfluid helium
Belina von Krosigk, Klaus Eitel, Christian Enss +9
To reach ultra-low detection thresholds necessary to probe unprecedentedly low Dark Matter masses, target material alternatives and novel detector designs are essential. One such t…
Radon Removal in XENONnT down to the Solar Neutrino Level
E. Aprile, J. Aalbers, K. Abe +169
The XENONnT experiment has achieved an exceptionally low Rn activity concentration within its inner 5.9tonne liquid xenon detector of (0.900.01stat.$\…
