For the Cryogenic Storage Ring (CSR) we are developing the molecule camera MOCCA, a micro-calorimeter based particle detector for mass-resolved detection of electrically neutral molecular fragments, originating from molecular-ion collisions on electrons, photons, etc. 3D imaging will be employed to determine the kinetic energy released in the fragmentation. Here the transverse position sensitivity is provided by the segmentation of the detector into 64 x 64 pixels onto a detection area of 45mm x 45mm. For impact time measurement on a ns scale we are developing a fast-timing-readout of secondary electrons. We discuss simulations of the employed electrostatic transport system, qualitatively approving the proposed concept and leading to a detailed mechanical design.
