High resolution mass spectrometry of exotic nuclei is an important tool to provide information about nuclear structure. Multiple reflection time-of-flight mass spectrometers (MR-TOF-MS) proved to be the perfect devices in particular for short-lived (≈ms) isotopes. For MR-TOF-MS it is necessary to have calibrant ions over a broad mass range and a high repetition rate(≈100 Hz). These requirements can be full-filled by the laser ablation carbon cluster ion source (LACCI), which is a part of the new diagnostics unit for the FRS Ion Catcher. The new diagnostics unit consists in addition of an RFQ based beam transport and distribution system, differential pumping sections and an RF Quadrupole mass filter. It will be integrated in 2018 in the beam line of the FRS Ion Catcher, which consists of a cryogenic stopping cell, a RFQ based beamline and a MR-TOF-MS. With LACCI a stable ( 10 hours) and high repetition rate (100Hz) ion production from different target materials is possible due to a 2D movable target table. The capabilities of the new diagnostics unit and first long term measurements with LACCI will be presented.
