The aim of the KATRIN project is to measure mass of the electron antineutrino with sensitivy at sub-electronvolt level. The experiment is based on the investigation of the electron spectrum of the beta-decay of tritium just at the beta-endpoint region. In this experiment the tritium cooled to low temperature is placed in the magnetic field of several tesla which causes weak but nonzero orientation of tritium nuclei and as the consequence, non-isotropic, on energy dependent, distribution of the beta-electrons.
