TITAN at TRIUMF: Ion traps for precision nuclear experiments

Abstract:  TRIUMF\'s Ion Trap for Atomic and Nuclear science (TITAN) exploits the textbook-like conditions and versatility of ion traps, which offer sophisticated manipulation of a single ion or a cloud, for beam preparation and high-precision measurements. To test the unitarity of the quarkmixing matrix, to understand stellar evolution, and to benchmark state-of-the-art predictions of the N = 32 subshell closure in titantium isotopes require mass spectrometry. On the other hand, in-trap decay spectroscopy has focused on investigations of the double beta-decay problem and is being extended to studies of electron influence on fundamental decays. A selection of recent results will be presented as well as technical developments useful at radioactive-ion-beam facilities.
