Results of the 2001 measurements of the Mainz neutrino mass experiment — •Christine Kraus, Jochen Bonn, Beate Bornschein, Lutz Bornschein, Fernando Conda, Björn Flatt, Beatrix Müller, Ernst Wilhelm Otten, Jean-Pierre Schall, Thomas Thümmler, and Christian Weinheimer — Institut für Physik, Johannes Gutenberg Universität Mainz, 55099 Mainz

The Mainz neutrino mass experiment investigates the endpoint region of the tritium β decay spectrum to determine the mass of the electron antineutrino. The principle of the Mainz spectrometer, Magnetic Adiabatic Collimation followed by a retarding Electrostatic Filter (MAC-E-Filter), combines both a high resolution and a large acceptance. After an optimal preparation of the apparatus, ≈ 2 month of data were taken. The data fit good together with the results of 98/99. The results of the analysis will be presented for the data of 2001 in combination with the 98/99 measurements.
