Description
Massive neutrinos impart an experimental signature in the endpoint region of beta-decay spectra. The KArlsruhe TRitium Neutrino (KATRIN) experiment uses a high-activity tritium source and a high-resolution spectrometer to place the most stringent upper limit on the effective neutrino mass of 0.8 eV/c^2 (90% CL). Experimental improvements and further data taking will bring KATRIN towards its final design goal of a sensitivity of 0.2 eV/c^2 (90% CL). Next generation experiments aim to use novel differential detectors and alternative beta-decay sources to push the sensitivity limit below the 0.1 eV/c^2 threshold.
