The spectroscopy of the prompt gamma decay from fission products gives information on the entry states, e.g. distribution functions for excitation energy and spin, and therefore a direct link to the fission process itself. This type of spectroscopy is, however, only possible when a filter can be constructed which allows to set a gate to the gamma- spectrum on a narrow region in mass and nuclear charge, as well as on part of the total excitation energy of the fragment split under investigation. A possible configuration of a prompt gamma-ray spectrometer consist of an gamma-ray array composed of high resolution germanium detectors, coupled to a gas filled magnet. In the presentation we will outline the principles for a gas filled magnetic spectrometer for fission product spectroscopy. In particular the focusing characteristics of such a device, which are valid for particles in the velocity regime of E/A<1MeV/amu, will be addressed. First experiments on the Lohengrin spectrometer in Grenoble investigating on the behaviour of fission products in gas filled magnets have been performed, and have validated the experimental approach to the nuclear fission process with such a device.
