The Cryogenic Storage Ring CSR at the Max Planck Institute for Nuclear Physics, Heidelberg, can store heavy molecular ions in their rotational and vibrational ground states, enabling the investigation of electron-ion interactions such as the dissociative recombination in laboratory environment under conditions close to those in cold interstellar plasmas. To reconstruct the full kinematics of these processes, position- and energy-sensitive coincident detection of multiple reaction products is necessary. For this purpose, MOCCA, a 4k-pixel molecule camera based on magnetic calorimeters with a detection area of 45 mm × 45 mm, was developed at the Kirchhoff-Institute for Physics in Heidelberg. We introduce a new readout scheme and present the plans for the integration of MOCCA and its 3He/4He dilution refrigerator into CSR, as well as a CSR-independent experimental setup where MOCCA will be used to study collision- and photon-induced ion fragmentation processes.
