Almost sixty years effort to determine the neutrino mass from experimental {beta}-ray spectra resulted recently in the model independent limit of m{sub v}<2.3 eV/c{sup 2}. The Karlsruhe Tritium Neutrino Experiment (KATRTN) should improve this limit to m{sub v}<0.2 eV/c{sup 2}, while the neutrino mass of 0.3 and 0.4 eV/c{sup 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.
