Bremsstrahlung photons, produced at superconducting electron accelerator ELBE at the
FZ Rossendorf will be used for the production of neutron-rich nuclei by photo-induced fission. The properties of such exotic nuclei will be studied by decay spectroscopy. The mass and charge identification plays a key role in such experiments and is based on a double time-of-flight (TOF) method for both fission fragments. The reaction products are registered using secondary electrons emitted by thin foils and detected by position-sensitive MCP detectors. Currently a position resolution of 1.8(0.3) mm (FWHM) in both x and y directions and a time resolution of about 330 ps (FWHM) have been deduced using a source of alpha-particles.
