Simulations of a stopping cell for the LEB of the Super-FRS at FAIR — •Daniel Schäfer1, Wolfgang R.

The low energy branch of the Super-FRS at the Facility for Antiprotons and Ions Research will be equipped with a cryogenic cell for stopping and extracting exotic nuclei produced by projectile fragmentation or fission, thus making them available for further experiments. This stopping cell has been developed and constructed at KVI, University of Groningen, Netherlands. Several computer models have been developed utilizing the ion trajectory simulation program. The design and basic features of the cell have been determined using these simulations, and optimal operating parameters have been found. Furthermore, simulations confirmed (semi-)analytical descriptions of ion collecting devices. Comparisons with first experimental results will be presented as well.
