Denver Whittington is principal investigator for a new five-year National Science Foundation CAREER award. His project, “Enhancing Future Liquid Argon Neutrino Experiments with Xenon” seeks to improve light collection and optical triggering of the Deep Underground Neutrino Experiment (DUNE) by investigating the co-doping of the Liquid Argon TPCs with very-low concentrations of Xenon, whose introduction into the liquid has the potential to improve significantly the optical performance of the DUNE detectors beyond what is possible with Liquid Argon alone.
