The Penning-trap mass spectrometer ISOLTRAP located at the radioactive ion beam facility ISOLDE at CERN performs high-precision mass measurements of short-lived nuclides. This gives access to the study of nuclear structure effects like the location of shell and sub-shell closures and beta-decay Q-values, providing tests of nuclear models and even the Standard Model of elementary particles. For three decades the measurement principle was based on a destructive time-of-flight ion cyclotron resonance detection method, which is reaching its limits now in accessible half-lives and relative uncertainties. With the new phase-imaging ion-cyclotron-resonance (PI-ICR) [PRL 110, 082501] detection technique, experiments can be performed with much less measurement time, providing access to new areas of the nuclear chart. This talk will report on the implementation of the PI-ICR technique as well as results from our first offline and online studies.
