Physical Review C, 2021•APSThe 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 of
its quenching factor for nuclear recoils. Our findings indicate it is indistinguishable from that
for sodium-doped CsI at room temperature. Additional properties such as light yield,
afterglow, scintillation decay properties for electron and nuclear recoils, and energy
proportionality are studied over the 108–165 K temperature range, confirming the vast …
