Precision mass measurements of short-lived isotopes at TITAN — •Jens Dilling — TRIUMF, Vancouver, Canada — University of British Columbia, Vancouver, Canada

The atomic mass is a fundamental property and acts as a fingerprint of the individual atom or isotope. The atomic mass also plays a vital role in our understanding of nature, ranging for example from the chemical element nucleosynthesis in the Universe to testing the nuclear strong force on a fundamental level. The most precise way to measure atomic masses is via ion traps and here in particular with so-called Penning traps. At the TRIUMF laboratory in Vancouver, we have developed very sensitive and fast methods using ion trap techniques at TITAN (TRIUMF's Ion Trap of Atomic and Nuclear science). The system is suited and optimized for accelerator-produced isotopes, capable of measurements of isotopes with 5ms half-lives and includes features for fast separation of contamination using a multi-reflection device. In this talk I will give an overview of ion trap mass measurement programs and provide an overview of the TRIUMF activities. I will also report on recent measurements with TITAN, as well as current developments.
