High-precision experimental data of ground-state properties of exotic nuclei allow testing the reliability of nuclear mass models. The TRIGA-TRAP experiment is a double Penning-trap mass spectrometer used to perform high-precision mass measurements of long-lived transuranium isotopes and short-lived fission-products at the research reactor TRIGA Mainz. Promted by a recent recharge of the superconducting magnet, the magnetic field has been mapped in detail, a new drift electrode section has been installed, and the whole setup was aligned and optimized with the help of a position-sensitive ion detector. First measurements with 197Au+ and carbon clusters were performed to investigate the performance and the magnitude of systematic effects. The current status and the latest results will be presented.
