  4. 4. Ionization efficiency at sub-keV energies for crystals and noble liquids
    Youssef Sarkis Mobarak (ICN-UNAM), Daniel Baxter (Fermi National Accelerator Laboratory)
    16/07/2022, 10:45

    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...

  5. 10. Background discrimination for low quanta events with NEWS-G
    Francisco Andres Vazquez de Sola
    16/07/2022, 11:10

    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...

  6. 11. Low-energy event excess in SuperCDMS HVeV detectors
    Dr Valentina Novati (Northwestern University)
    16/07/2022, 11:35

    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...

  7. 2. Skipper-CCDs performance in CONNIE
    CONNIE collaboration

    The Coherent Neutrino-Nucleus Interaction Experiment (CONNIE), located at sea level at about 30 m from the core of the 3.8 GW Angra 2 nuclear reactor in Brazil, aims to detect the coherent elastic scattering of reactor antineutrinos (CEvNS). The experiment has operated from 2016 to 2020 using 12 fully depleted high-resistivity 4k x 4k CCDs (Charge Coupled Devices) with 6 g each, with a readout...
