The LiquidO collaboration has published the results of its first experimental validation on the "Communications Physics" website of Nature*. This detection technique which uses an opaque liquid scintillator with a dense network of optical fibers opens new detection perspectives in the field of neutrinos, but also in many other disciplines.

LiquidO is a new detection technique that uses opaque scintillators to visualize particle interactions down to the centimeter scale. It works with the abundant light produced by the scintillators, but could also exploit Cherenkov radiation. The technique can be optimized for a wide range of detector sizes and neutrino energies, from the GeV to the MeV scale, and accommodates very well the presence of doping elements at concentrations far exceeding those allowed in traditional scintillator detectors.

Its performance gives it a wide range of applications in many areas of high energy, nuclear, medical and gas pedal physics, many of which are being actively explored.* Neutrino physics with an opaque detector , Commun Phys 4, 273 (2021)---> https://www.nature.com/articles/s42005-021-00763-5Contact: Frederic Yermia (yermia@subatech.in2p3.fr), Neutrino team, Subatech

The opaque medium of the detector allows to confine the light locally where the energy deposits occur and thus to access the precious topological information of the event. Image: LiquidO Collaboration
