Study of the tritium beta-spectrum in experiment 'Troitsk nu-mass'

Status and perspectives of the search for the neutrino mass by means of direct kinematics approach in tritium beta decay are presented. Results of last years measurements of end point region of tritium spectrum on the “Troitsk ν-mass” set-up are given. Last data provide some new features of bump-like anomaly at the end of the spectrum, which was observed earlier. The set up was upgraded by construction on-line isotope separator and additional stage of differential pumping in the tritium source, thus enabling to double tritium source intensity with lower background.
