The Cryogenic Storage Ring at the Max Planck Institute for Nuclear Physics in Heidelberg is able to store heavy molecular ions in their rotational and vibrational ground states. In a near future electron-ion-interactions, such as the dissociative recombination, will be investigated in laboratory environment at conditions that are close to those in cold interstellar plasmas. To reconstruct the full kinematics of these processes, a position and energy sensitive coincident detection of multiple reaction products is necessary. We recently designed and fabricated MOCCA, a 4k-pixel molecule camera based on magnetic calorimeters with a detection area of 45 mm × 45 mm segmented into 64×64 absorbers. We present the detector design and microfabrication as well as the plans for integrating MOCCA and its 3He/4He dilution refrigerator into CSR.
