A compact method of detecting neutrinos provides new tests of physics theories and could lead to new reactor-monitoring methods.
Neutrinos are typically detected through coherent elastic neutrino-nucleus scattering (CEvNS), a process in which neutrinos interact with the entire nucleus rather than just a proton or electron.
A team of researchers has developed a neutrino detector made of germanium crystals. When they installed the detector at the Leibstadt reactor in Switzerland, it caught 400 antineutrinos in 119 days.
