Super-FRS Ion Catcher - Overview and Progress — •Jamie Harkin for the Super-FRS Experiment collaboration — Justus-Liebig-Universität Gießen

The Super-FRS Ion Catcher (Super-FRS-IC) setup will enable the measurements of beta-delayed (multiple-)neutron emission probabilities (Pxn) i.e., data for r-process nucleosynthesis models that is lacking the most. Moreover, the setup will study multi-nucleon transfer (MNT) reactions driven by secondary beams as a promising method for accessing the unexplored heavy neutron-rich nuclei. These topics will be in focus in the Early- and First-Science programs at the Super-FRS at FAIR. The Super-FRS-IC will also provide thermalized, low emission beams to the LaSpec and MATS experiments. With the Super-FRS-IC, the exotic nuclei produced at relativistic energies and separated in-flight will be thermalized in the Cryogenic Stopping Cell (CSC), transported over a radio frequency quadrupole (RFQ) beamline and analyzed in the Multiple-Reflection Time-Of-Flight Mass-Spectrometer (MR-TOF-MS). This contribution presents the status of the construction of the Super-FRS-IC and an outlook to the experiments to be performed.
