VIRTUAL INPA SEMINAR | Scott Kravitz (LBNL)

Speaker: Scott Kravitz (LBNL)    Title: CrystaLiZe - Solid Xenon Detector R&D   Abstract:  Radon and its daughter decays limit the sensitivity of direct WIMP dark matter searches, despite extensive screening programs, careful material selection and specialized Rn-reduction systems. For xenon time projection chambers, a means to surpass this constraint may lie in crystallizing the xenon. In […]
