The set-up consists ofa deflecting magnet, an array of focal plane detectors, the data acquisition system and newbeam-line components. The system provides tagged photons in an energy range from 6 MeVto 20 MeV with the emphasis on best possible resolution and intensity. The absolute energyresolution of photons at 10 MeV is better than 25 keV. With the current focal-plane detectors a4maximum rate of tagged photons of 10 /(keVs) can be achieved. An upgrade to more than510 /(keVs) with an alternative detector array is under investigation.The design values mentioned above are the requirements for planned experiments in thefields of nuclear astrophysics and nuclear structure.
