The CSR-ReMi is a newly installed in-ring reaction microscope for experiments with slow and cold molecular or cluster ions in the cryogenic storage ring CSR [1]. A reaction microscope (ReMi) is a combined electron and ion spectrometer [2, 3]. It offers multi-hit capability and provides high detection efficiency, acceptance and resolution. With the coincident detection of all collision fragments kinematically complete data-sets on the reaction dynamics can be collected. The integration of the CSR-ReMi into the CSR was finalized in July 2023 and first commissioning experiments under cryogenic conditions were performed recently. Emphasis was given to electron-transfer and electron-loss reactions in collisions of various types of stored ions with neutral atoms or molecules that were injected by a supersonic gas jet. Selected results of these first experiments will be presented.
