Reflecting the sum of all interactions inside a nucleus, its mass is an important characterizing property. Precisely known nuclear masses are an integral part in several different fields of fundamental science. Calculations of the astrophysical r-process, nuclear structure studies, and investigations of fundamental interactions require mass measurements of rare isotopes. Mass data of highest precision is obtained by Penning trap mass spectrometers such as LEBIT located at the National Superconducting Cyclotron Laboratory. The rare isotopes of interest are produced by heavy-ion fragmentation and subsequent in-flight separation and delivered to LEBIT which uses the destructive time-of-flight ion cyclotron resonance technique. As one moves further from the valley of stability, production rates of the exotic isotopes decline. In order to access rare isotopes being delivered at low rates, the Single Ion Penning trap is being developed using the FT-ICR technique.
We report on the present status of the SIPT development and also emphasize the impact of mass measurements with LEBIT on the topics of nuclear structure and fundamental interactions.
