Topical Workshop for WP3: Target Properties

Thursday 26 Sept 2024, 12:00 → 20:00 Europe/Zurich

WP 3.1 will focus on advancing research in hybrid Cherenkov/scintillator systems, opaque scintillators, and isotope loading for neutrinoless double-beta decay (0νββ) searches and neutron tagging.

WP 3.2, on the other hand, aims to further explore the significant potential of noble liquids in astroparticle and particle physics, from eV to GeV energy range, and in medical applications.
