Experimental Particle and Astro-Particle Physics Seminar

Monday 8 Nov 2021, 14:00 → 16:00 Europe/Zurich

Abstract: Experimental efforts in coherent elastic neutrino nuclear scattering (CEvNS) have gained significant momentum over the last few years, since the first observation of the CEvNS reaction at the Spallation Neutron Source (SNS).  Observing reactor CEvNS remains a milestone of interest in neutrino physics, with implications for basic science and nonproliferation reactor monitoring regimes.  In this talk, we discuss a concept for an entirely passive, small, solid CEvNS detector that uses color center defects induced by CEvNS reactions in a crystal and light-sheet microscopy to obtain a signal. This concept, inspired by so-called "paleo-detectors" for astrophysical neutrinos and dark matter candidates, presents intriguing possibilities for a simpler low-threshold CEvNS or dark matter detector, or even a high-quality neutron detector.  We will also review how this might be used for doing basic science physics with CEvNS at reactors, for dark matter detection, as a neutron detector for nuclear warhead verification, or to monitor nuclear reactors as part of international and multi-lateral security agreements.
