Available in PDF, EPUB and Kindle. Book excerpt: An experiment to study the beta-decay of tritium using a gaseous source of free (unbound) atomic tritium is currently underway in the Physics Division at Los Alamos. The use of free atomic tritium along with careful design of the measurement scheme should allow a definitive determination for an electron antineutrino mass approx. 10 eV.

Book excerpt: An apparatus is under construction at Los Alamos to measure the beta spectrum of free tritium atoms and molecules. The tritium atoms decay in a gaseous windowless source and are analyzed by a Tret'yakov type toroidal field beta spectrometer. The ultimate sensitivity of the experiment to electron antineutrino mass is expected to be

Available in PDF, EPUB and Kindle. Book excerpt: An initial measurement of the tritium beta spectrum spanning an energy range of 16.4 - 18.9 keV has been performed using a free molecular tritium gas source. With the data from this preliminary low statistics measurement (approx. 72 hours of data), we are able to set an upper limit on the electron-antineutrino mass of 36 eV at the 95% confidence level. Measurements with a gaseous source eliminate many of the ambiguities arising from uncertainties associated with solid-source-based measurements. The ultimate neutrino mass sensitivity of our system should be about 10 eV or less. 13 refs., 9 figs.

Available in PDF, EPUB and Kindle. Book excerpt: The beta spectrum of the decay of free molecular tritium has been accurately measured in order to search for a finite anti nu/sub e/ mass. The betas originating from the decay of free tritium molecules in a differentially pumped source region were momentum analyzed in a toroidal beta spectrometer with 36-eV resolution. The final state effects in molecular tritium are accurately known and the data thus allow us to set an upper limit of 29.3 eV on the anti nu/sub e/ mass at the 95% confidence level.

Available in PDF, EPUB and Kindle. Book excerpt: Measurements near the endpoint of the tritium beta-decay spectrum using a gaseous molecular tritium source yield an essentially model-independent upper limit of 27 eV on the /ovr .nu.//sub e/ mass at the 95% confidence level. Since demonstrating from this initial measurement the successful operation of a gaseous source based system, most of our effort has been concentrated towards the upgrade and optimization of the experimental apparatus. The emphasis of this work has been to eliminate or further reduce effects that generate systematic errors. Based on realistic projections from our initial measurement, an ultimate sensitivity to neutrino mass of 10 eV is expected. 12 refs., 1 fig.
