Review on Low-Energy Excess Signals Observed in Cryogenic Rare Event Search Experiments
Review on Excess Signals Observed in CCD Detectors
We study the ionization and light yields produced by nuclear recoils at low
energies in pure crystals and noble liquids in the context of Lindhard's
integral equation, incorporating the effects of binding energy, improved
modeling of the electronic stopping, and electronic straggling. We
consider three different models for the electronic stopping power that
incorporate Coulomb repulsion...
The New Experiment With Sphere-Gas (NEWS-G) employs spherical proportional counters (SPC) filled with gas to search for elastic scattering of WIMPs off light target nuclei, reaching sensitivities down to single ionisation electrons. The new-generation detector consists of a larger sphere of 140 cm diameter, equipped with a new multi-anode sensor, ”ACHINOS”, developed to ensure a sufficiently...
The 1-gram silicon HVeV detectors developed within the Super Cryogenic Dark Matter Search (SuperCDMS) collaboration have achieved single-photon sensitivity and a baseline resolution of $\sigma=2.7$ eV. These cryogenic calorimeters can be operated in two configurations: (1) as phonon-assisted charge amplifiers by exploiting the Neganov-Trofimov-Luke (NTL) effect; (2) without NTL voltage (0V) by...
