The TRIGA-SPEC experiment - comprising the collinear laser spectroscopy setup TRIGA-LASER and the double Penning-trap mass spectrometer TRIGA-TRAP - allows determining ground-state properties of exotic nuclei. On-line coupling to the research reactor TRIGA Mainz offers the possibility to perform high-precision measurements on short-lived nuclides produced by neutron-induced fission of U-235. Fission products are extracted by an aerosol-based gas-jet system, collimated by an aerodynamic lens and guided through a skimmer system to a high-temperature surface ion source. To improve the ionization efficiency, a new ion source is beeing bulit in collaboration with JAEA Tokai, Japan. An overview of the current status will be given.
