Scintillation response of cryogenic CsI to few-keV and sub-keV nuclear recoils

J. I. Collar, C. M. Lewis, A. Simón +1

Monochromatic neutron emissions from photonuclear sources Y/Be and Sb/Be are employed to obtain the response of pure (undoped) cesium iodide at 80 K. The use of a lo…

Comment on "Final CONUS results on coherent elastic neutrino nucleus scattering at the Brokdorf reactor"

J. I. Collar, C. M. Lewis

We describe several omissions and deficiencies in the arguments presented by Ackermann et al. (arXiv:2401.07684), pointing at missing information necessary to back up its conclusio…

Search for a Non-Relativistic Boson in Two-Body Antimuon Decay

J. I. Collar, P. S. Cooper, C. M. Lewis

We demonstrate the feasibility of probing the charged lepton flavor violating decay for the presence of a slow-moving neutral boson cap…

Particle Physics at the European Spallation Source

H. Abele, A. Alekou, A. Algora +176

Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will be the world's brightest neutron source. As such, it has the potential for a particle physic…

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…

Measurement of Coherent Elastic Neutrino-Nucleus Scattering from reactor antineutrinos

J. Colaresi, J. I. Collar, T. W. Hossbach +2

The 96.4 day exposure of a 3 kg ultra-low noise germanium detector to the high flux of antineutrinos from a power nuclear reactor is described. A very strong preference ($p<1.2\tim…

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…
