Book excerpt: It has been nearly eight years since the group led by Lubimov first saw evidence for a finite neutrino mass in the tritium beta decay spectrum. Their measurement provided a great stimulus to the field; the number of experiments currently underway reflects the significance of their claim. The fact that further data are only now beginning to appear reflects the difficulty of this measurement. As an introduction to related papers in these proceedings, we briefly consider the key elements involved in neutrino-mass measurements using tritium beta decay and list the experiments currently underway in the field. 5 refs., 1 tab.

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.

Book excerpt: Reviews the current state of knowledge of neutrino masses and the related question of neutrino oscillations. After an overview of the theory of neutrino masses and mixings, detailed accounts are given of the laboratory limits on neutrino masses, astrophysical and cosmological constraints on those masses, experimental results on neutrino oscillations, the theoretical interpretation of those results, and theoretical models of neutrino masses and mixings. The book concludes with an examination of the potential of long-baseline experiments. This is an essential reference text for workers in elementary-particle physics, nuclear physics, and astrophysics.

This book was released on 2004 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: For decades people have tried to measure the rest masses of the neutrinos, but this quest has not yet been successful. The most commonly used method to determine the rest mass of the electron anti-neutrino is to measure the high energy end of the tritium beta decay spectrum. Various experiments suffered from conceptional problems, so that currently only an upper limit of 2.3 eV is known for the rest mass of the electron anti-neutrino. The Neutrino Experiment at the University of Texas (NEXTEX) has been thoroughly designed to avoid many problems that have been encountered in former attempts to measure the rest mass. The goal of NEXTEX is to lower the upper limit to less than 0.8 eV and by doing so possibly measure the rest mass of the electron anti-neutrino for the first time. The tritium recycling system is an important part of this experiment and the purpose of this thesis is not only to describe this recycling system in detail, but also to provide information about various potential problems that might arise and how they have been solved. These potential problems include catalysts, unwanted surface reactions and the solubility of tritium in Fomblin. The latter has just recently been investigated and a great deal of attention will therefore be dedicated to the presentation of the latest results.
