Experimental data on ground-state properties of exotic nuclei are of interest for nuclear structure studies and allow testing the predictive power of nuclear mass models. Besides off-line measurements on long-lived transuranium isotopes, high-precision mass measurements on short lived nuclides can be performed at TRIGA-TRAP, thanks to the on-line coupling to the research reactor TRIGA Mainz. Neutron rich nuclides are produced by neutron-induced fission of U-235 inside the reactor, extracted by an aerosol-based gas-jet system and guided through a skimmer system to a high-temperature surface ion source. To improve the ionization efficiency, a new ion source has been successfully implemented in collaboration with JAEA/Tokai. An overview of the current status and latest results on the performance will be presented.
