Neutrino Physics Opportunities at ORNL
The Physics Division at ORNL is exploring key opportunities for neutrino physics and supporting the formation of an experimental program at the intersection of particle, nuclear, and astrophysics. The Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR) of ORNL are two very powerful neutrino sources that open new physics opportunities. Two new experiments, PROSPECT and COHERENT, make use of these unique capabilities and enable us to broaden the understanding of neutrino properties. PROSPECT consists of segmented 6Li-loaded liquid scintillator antineutrino detectors designed to probe short-baseline neutrino oscillations and precisely measure the reactor antineutrino spectrum. The COHERENT collaboration aims to measure CEvNS (Coherent Elastic Neutrino-Nucleus Scattering) at the SNS. The CEvNS process is cleanly predicted in the Standard Model and its measurement provides a Standard Model test. I will present a novel neutrino experiment which consists of a differential measurement of coherent-elastic neutrino-nucleus scattering using isotopically enriched Ge detectors. I will review some of the current activities taking place at ORNL including the development of ultrasensitive analytical techniques to detect trace elements of interest for neutrinoless double beta decay experiments and will present recent results.
