An overview of Cryogenic CsI — a future COHERENT detector*

COHERENT collaboration is the first that observed Coherent elastic neutrino-nucleus scatter (CEvNS) events in 2017. A 14.6 kg doped CsI at room temperature was placed 20 meters away from the 1.4 MW Spallation Neutron Source (SNS) at the Oak Ridge National Laboratory (ORNL). The SNS pulsed proton beam provides a uniquely high background rejection and high-intensity neutrino source. CryoCsI is a cryogenic CsI scintillating detector, which potentially has a much lower energy threshold down to 0.4 keVnr. Working with other COHERENT detectors, CryoCsI can produce world-leading sensitivities on broad physics topics, such as inelastic neutrino-nucleus interactions, searches for accelerator-produced dark matter (DM) and physics beyond the Standard Model.
