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 ${}^{88}$Y/Be and ${}^{124}$Sb/Be are employed to obtain the response of pure (undoped) cesium iodide at 80 K. The use of a lo…
