A novel four-Penning trap system designed for mass measurements of highly charged stable and radioactive nuclides is currently planned and under construction in a GSI - University of Mainz Collaboration. High-precision mass values are required in many fields of physics. Since the required upper limit of the uncertainty differs from 10−7 in nuclear physics down to below 10−11 in metrology and for new determinations of fundamental constants, a further development of Penning trap mass spectrometers opens new applications for atomic masses in these very active fields of physics [1]. However, new cooling and detection techniques for exotic nuclei far from stability are needed to use highly charged and rarely produced specie at radioactive ion beam facilities efficiently. To this end we develop a new four-trap mass spectrometer with single-ion-sensitivity dedicated to highly charged rare isotopes delivered by the HITRAP facility at GSI. The design studies as well as the present status of the project will be presented.
