Comments on "Direct measurement of the ionization quenching factor of nuclear recoils in germanium in the keV energy range"
J. I. Collar, C. M. Lewis
We examine a recent measurement of the quenching factor (QF) in germanium at 80 K, noticing a number of inconsistencies capable of affecting a claimed agreement with Lindhard's ion…
First results from a search for coherent elastic neutrino-nucleus scattering (CENS) at a reactor site
J. Colaresi, J. I. Collar, T. W. Hossbach +4
The deployment of a low-noise 3 kg p-type point contact germanium detector at the Dresden-II power reactor, 8 meters from its 2.96 GW core, is described. This location provi…
Germanium response to sub-keV nuclear recoils: a multipronged experimental characterization
J. I. Collar, A. R. L. Kavner, C. M. Lewis
Germanium is the detector material of choice in many rare-event searches looking for low-energy nuclear recoils induced by dark matter particles or neutrinos. We perform a systemat…
Response of undoped cryogenic CsI to low-energy nuclear recoils
C. M. Lewis, J. I. Collar
The bright scintillation of pure CsI operated at liquid-nitrogen temperature makes of this material a promising dark matter and neutrino detector. We present the first measurement…
Coherent Elastic Neutrino-Nucleus Scattering at the European Spallation Source
D. Baxter, J. I. Collar, P. Coloma +12
The European Spallation Source (ESS), presently well on its way to completion, will soon provide the most intense neutron beams for multi-disciplinary science. Fortuitously, it wil…
