dc.description.abstractThe KArlsruhe TRItium Neutrino experiment KATRIN aims at improving the upper limit of the mass of the electron antineutrino to about 0.2 eV (90% c.l.) by investigating the beta-decay of tritium gas molecules T(2) -> ((3)HeT)(+) + e(-) + (nu) over bar (e). The experiment is currently under construction to start first data taking in 2012. One source of systematic uncertainties in the KATRIN experiment is the formation of ion clusters when tritium decays and decay products interact with residual tritium molecules. It is essential to monitor the abundances of these clusters since they have different final state energies than tritium ions. For this purpose, a prototype of a cylindrical Penning trap has been constructed and tested at the Max-Planck-Institute for Nuclear Physics in Heidelberg, which will be installed in the KATRIN beam line. This system employs the technique of Fourier-Transform Ion-Cyclotron-Resonance in order to measure the abundances of the different stored ion species.es_ES
dc.description.sponsorshipThe two Penning traps have been financed by the BMBF (grant to the University of Karlsruhe) under project codes 05CK5VKA/5 and 05A08VK2. The support of the Deutsche Forschungsgemeinschaft for the development of the FT-ICR detection technique for precision mass spectrometry under contract number BL981-2-1 is gratefully acknowledged. We thank A. Gotsova for her help during tests in Mainz and Prof. C. Weinheimer for useful discussions related to this project. We warmly thank the LPC trappers group for providing the attenuation grids. D. Rodríguez is a Juan de la Cierva fellow and acknowledges support from the Spanish Ministry of Science and Innovation through the José Castillejo program to provide funding for a 5-month stay at the MPI-K. Sz. Nagy acknowledges support from the Alliance Program of the Helmholtz Association EMMI. S. Lukic acknowledges support by the Transregional Collaborative Research Centre No. 27 “Neutrinos and Beyond”, funded by Deutsche Forschungsgemeinschaft.es_ES
