Mass spectrometry as a tool for nuclear structure and astrophysics studies at TRIUMF — •Timo Dickel for the TITAN collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH — Justus-Liebig-Universität Giessen

A high-performance multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) is used for mass measurements of exotic nuclides at the TITAN experiment at the ISOL facility ISAC at TRIUMF, Canada. The system was developed at Justus Liebig University Gießen. The increased sensitivity due to very high efficiency and a novel method for background suppression applied in this MR-TOF-MS allows nuclear structure and nuclear astrophysics studies at the extremes of the nuclear chart. A wide range of results will be presented, from investigations of the astrophysical scenario of the r-process to nuclear structure effects like the island of inversion or the shell structure at the outskirts of the nuclear chart. Moreover, the first discovery of an isotope with an MR-TOF-MS will be discussed.
