The FRS Ion Catcher, a test branch for the Super-FRS at FAIR, is comissioned and successfully tested. Consisting of a Cryogenic Stopping Cell (CSC), a diagnostic unit (DU) and a Multi-Reflection Time-of-Flight Mass-Spectrometer (MR-TOF-MS) to stop, identify and measure projectile and fission fragments produced by the FRS.
To do systematic studies of the MR-TOF-MS calibrants over a broad mass range are essential. To fulfil this task a laser ablation carbon cluster ion source has been designed, commissioned and tested in an external setup. Advantages of this source is a broadband mass range of calibrants (clusters), generation calibrants at every mass unit (C-13 enriched fullerenes), a high repetition rate (100Hz) and long term stable operation (x-y-table). Due to that it is a perfect tool to complete the current setup of the MR-TOF-MS. First tests and results will be presented.
