NPA Seminar (virtual): Jan Behrens, KIT, "The KATRIN experiment: The Challenge of Determining the Absolute Neutrino Mass"
The KArlsruhe TRItium Neutrino experiment probes the absolute neutrinomass scale via the β-decay kinematics of molecular tritium. With a sensitivity goal of 0.2 eV/c² at 90% CL, it provides model-independent input to both particle theory and cosmology. The source is highly pure, cryogenic T₂ gas. The electrons resulting from β-decay are guided along magnetic field lines toward a high-resolution, integrating spectrometer for
