Description
TRIUMF's Ion Trap for Atomic and Nuclear science (TITAN) operates several ion traps for high-precision mass measurements and spectroscopy. Among these traps is a Multi-Reflection Time-Of-Flight Mass Spectrometer (MR-TOF-MS) for mass measurement and isotope selective cleaning of beam for other traps. TITAN's MR-TOF-MS has demonstrated excellent dynamic range ($\sim10^8$) and high-precision ($\frac{\delta m}{m} \approx 10^{-7}$) allowing for measurement of very exotic isotopes. Presented here are a set of mass measurements clarifying the nuclear structure near N=34 in potassium.
Recently we developed new techniques enabling the measurement of half-lives using the MR-TOF-MS. This has allowed for half-life measurements of isotopes ranging from $\sim$10 ms and $\sim$5 min. In addition to providing supplementary data for identification of species, this new measurement technique has allowed for several first time half-life measurements and improved half-life uncertainties. The TITAN MR-TOF-MS's re-trapping and ion by ion mass and decay measurement abilities have proven to be powerful tools for half-life and mass measurements of exotic low rate species in a high background environment. The implications of these and future half-life measurements for nuclear structure and nucleosynthesis will be discussed.
