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

At the Super-FRS-IC, the exotic nuclei produced at relativistic energies and separated in-flight will be thermalized in the Cryogenic Stopping Cell (CSC). The new CSC for the Super-FRS, currently under construction, features a High Areal Density Orthogonal (HADO) design, achieving an areal density of cryogenic helium (He) exceeding 25 mg cm^(-2) - a four-fold increase over existing systems. The stopping cell chamber (split into stopping and extraction regions), will be nested inside a larger insulating vacuum chamber. The beam will be delivered through air and two thin (100 micron) aluminium beam windows. Investigations into the deformation caused by the pressure differential between the regions; resulting energy deposition difference relative to beam position in the beam windows; optimizing thermal coupling between the cryo-coolers and the cryo-cell; ideal potentials of the DC push electrodes in the stopping region have been conducted. This poster presents these results, and the status of construction.
