The neutrino discovery by Reines & Cowan (1956) paved the technical ground behind the establishment of much of today’s neutrino detection. Large instrumented volumes have been achieved via a key implicit principle: the impeccable transparency of detector. Much of that technology has yielded historical success, including several discoveries, such as the “neutrino oscillation” phenomenon leading to an important modification of the Standard Model of Particle Physics. Despite their remarkable success, much of that technology is also known to suffer from some key limitations, even after 70 years of maturity towards perfection. Indeed, particle identification is improvable, else forcing experiments to rely on cumbersome and expensive external shield (active or passive) setups, including major overburden in underground laboratories, to mitigate the otherwise overwhelming backgrounds.
In this seminar, I shall introduce the novel LiquidO technology — in final stages of demonstration and consolidation — relying heavily, for the first time, on light detection in “opaque” media. The goal is to enable sub-atomic particle event-wise imaging, so event topology and fast-timing may be use for particle ID purposes even at MeV energies. The development is led by the homonymous international academic consortium, with institutions from over 11 countries. The seminar will finish with some highlights of the upcoming LiquidO-based experiments, namely the AntiMatterOTech (EIC+UKRI) and the CLOUD experiment.
