The low temperatures and low gas densities in cold interstellar clouds allow the present molecules to relax into their vibrational and rotational ground states. At the Max Planck Institute for Nuclear Physics in Heidelberg, these conditions can be reproduced in the Cryogenic Storage Ring CSR, where heavy molecular ions can cool down while stored for thousands of seconds and electron-ion recombination can be investigated. To reconstruct the full kinematics of these processes, position- and energy-sensitive coincident detection of multiple neutral reaction products is required. For this purpose, MOCCA, a 4k-pixel molecule camera based on metallic magnetic calorimeters with a detection area of 45 mm × 45 mm, was developed at the Kirchhoff Institute for Physics in Heidelberg. We present the detector readout scheme, characterization measurements, and the implementation of MOCCA into the CSR-independent MOCCA standalone setup, that will be used to study photon- and collision-induced ion fragmentation processes before MOCCA will be integrated into CSR.
