Almost sixty years effort to determine the neutrino mass from experimental x-ray spectra resulted recently in the model independent limit of m(nu) < 2.3 eV/c(2). The Karlsruhe Tritium Neutrino Experiment (KATRIN) should improve this limit to m(nu) < 0.2 eV/c(2), while the neutrino mass of 0.3 and 0.4 eV/c(2) should be seen as 3.5 and 6.5 sigma effect, respectively. Some details of the KATRIN setup, including the windowless gaseous tritium source and a tandem of two electrostatic retarding spectrometers with adiabatic magnetic collimation, are outlined.
