Scientists observe the tritium beta decay process, where a tritium nucleus decays into helium, an electron, and an antineutrino.
A giant 200-tonne spectrometer measures the energy of the emitted electrons. By analyzing the maximum energy (endpoint) of these electrons, the mass of the "missing" neutrino is inferred. 3. Key Findings (2021 Status) katrin [2021-07-09 18-28-07].mp4
KATRIN: Neutrinos are lighter than 0.8 electronvolts - sfb1258 Scientists observe the tritium beta decay process, where
KATRIN Experiment (Karlsruhe Institute of Technology) Date Reference: July 2021 Analysis Phase 1. Executive Summary katrin [2021-07-09 18-28-07].mp4
The analysis utilized approximately 36 million electron events collected between 2019 and 2021.
Below is a draft "paper" summarizing the key findings and significance of the KATRIN experiment as of mid-2021, which would have been the focus of recordings from that date.
