COSINUS (Cryogenic Observatory for Signals seen in Next‑generation Underground Searches) develops cryogenic scintillating calorimeters with NaI target crystals to provide a model‑independent cross‑check of the DAMA/LIBRA result. Because hygroscopic NaI cannot withstand direct deposition of a tungsten transition‑edge sensor (W‑TES), COSINUS employs the remoTES design, in which the TES is...

Scintillating crystals are among the most widely used particle detectors in research laboratories, industry, nuclear medicine, and physics experiments. Some of these tend to degrade when exposed to environmental humidity, such as NaI(Tl). This makes the crystals difficult to handle, can limit their use in specific applications or forces the selection of alternative materials with suboptimal...

The direct search of dark matter is a mature field in which performing improvements in sensitivity is utterly challenging. Besides scaling up the size of detectors, the most promising approach is the reduction of backgrounds.

In Coherent Elastic Neutrino–Nucleus Scattering (CEνNS), a neutrino scatters coherently off an entire nucleus via a weak neutral-current interaction, producing a low‑energy nuclear recoil, typically in the sub‑keV range for reactor antineutrinos. As such, CEνNS represents both a powerful probe for neutrino physics and an irreducible background for direct dark matter searches, where nuclear...

Low-energy excess (LEE) is a common phenomenon in various solid-state detectors, acting as a significant limiting factor for rare event searches [1]. These anomalous signals create an unwanted noise floor that masks weak interactions, complicating the distinction between true dark matter signals and its backgrounds.
