First experimental demonstration of the LiquidO
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.

Installation of the DAMIC-M prototype
A prototype of the DAMIC-M detector was installed in December 2021 in the Modane underground laboratory in the Frejus tunnel. First results from the joint work of researchers and PhD students from Subatech and LPNHE laboratories, the University of Chicago and the University of Washington, are expected in the coming months.

AMO-TECH a project funded under the EIC Pathfinder Open call
The new European Innovation Council, which emerged under the Horizon Europe 2021-2027 programme, opened its first Pathfinder Open call in 2021. A project led by researchers from IN2P3 (IJCLab) and the University of Nantes (SUBATECH) was accepted under this tool for funding disruptive technological research projects:
AMO-Tech (AntiMatter-OTech Novel Opaque Scintillator Technology for Nuclear Industry Imaging based on Anti-Matter Detection), teams from IJCLab (Anatael Cabrera, IN2P3) and SUBATECH (Frédéric Yermia, Université de Nantes). The European Consortium partners are CIEMAT (Spain), the University of Sussex (UK) and EDF as industrial partner. The project aims to monitor a reactor core and provide assistance in the dismantling of reactors. It is based on the R&D programme Liquido, an innovative deep-tech detector for fundamental physics of antineutrinos and charged particles. The detection principle will be published in the journal Nature Physics Communication. The programme will take place at the Chooz power plant in the Ardennes. It is scheduled to start in 2022.
