The 2021 data confirmed that neutrinos are at least one million times lighter than electrons.
Unlike cosmological observations, this measurement is direct and model-independent , meaning it does not rely on assumptions about the early universe. 4. Significance for Physics katrin [2021-07-09 18-28-07].mp4
KATRIN Experiment (Karlsruhe Institute of Technology) Date Reference: July 2021 Analysis Phase 1. Executive Summary The 2021 data confirmed that neutrinos are at
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) this measurement is direct and model-independent
The measurement is conducted at the using a 70-meter-long beamline.
