Status of the low-energy electrostatic cryogenic storage ring (CSR) at MPI-K in Heidelberg.

Author(s) : HAHN R., FADIL H., GRIESER M., et al.

Summary

At the Max-Planck-Institute for Nuclear Physics in Heidelberg a next-generation electrostatic storage ring for atomic and molecular ion beams is under construction. In contrast to existing electrostatic storage rings, the authors' CSR will be cooled down to temperatures below 2 K. The low-temperature storage ring walls decisively reduce the influence of black-body radiation incident onto the stored particles such that only the lowest rotational levels will be occupied in radiatively active molecular ions. Completely new classes of experiments will become feasible exploring e.g. the interaction of rovibrational state-controlled molecular ions, clusters with ultra-low energy electrons, ultrafast or high-precision (IR,VUV) lasers, with atoms or cold neutral molecules. Moreover, due to the excellent vacuum of up to 10-15 mbars highly charged (radioactive) ions or antiprotons can be stored as well, pointing to novel experiments at the upcoming facilities at the GSI, Darmstadt. In this paper the status of the project is reported, focusing on the cryogenic concept.
