  Title Scintillation response of cryogenic CsI to few-keV and sub-keV nuclear recoils Type Journal Article
  Year 2026 Publication Physical Review C Abbreviated Journal Phys. Rev. C  
  Volume 114 Issue 3 Pages 034607 - 7pp  
  Keywords  
  Abstract Monochromatic neutron emissions from photonuclear sources 88Y /Be and 124Sb /Be are employed to obtain the response of pure (undoped) cesium iodide at 80 K. The use of a low-noise, high-quantum-efficiency avalanche photodiode in combination with a novel wave shifter results in a 70 eV analysis threshold. This reach allows us to observe signals from sub-keV nuclear recoils originating in neutron scattering. The extracted quenching factor drops much faster towards low energy than the extrapolation of a model developed for room-temperature CsI[Na]. We comment on the impact of our measurement on planned use of cryogenic CsI in neutrino physics and dark matter experiments.
