Troitsk-n-Mass Setup

The existence (and the magnitude) of the neutrino mass is of fundamental significance both for understanding the nature of elementary particles and for developing knowledge of the Universe structure. For this experiment (Troitsk Neutrino Mass Experiment) a unique high-resolution beta-spectrometer on the basis of a large superconducting magnetic trap has been designed. Measurements of many years have given the best world's result: the electron antineutrino rest mass doesn't exceed 2.3 eV/sec² at a 95% confidence level.
