  abstract  = {Cryopumps without liquid nitrogen shielding are used to provide a vacuum of 10-6 torr in the spectrometer. The vacuum system is subdivided in three sections that can be separated by valves. The first section (scattering chamber) has a volume of 60 l, two rotation transmissions with 35 cm dia and a sliding seal that allows a rotation of 160° without deteriorating the vacuum. The second section includes the vacuum chambers inside the magnets with 6 × 80 cm cross-section and a length of 1200 cm. The third section (detector box) has a volume of 4300 l and contains a moveable detector system. The gas inside the detector with a pressure of 760 torr is separated from the vacuum by a 15 μm mylar foil with an area of 300 cm2. The detector box can be valved off by a valve with the dimension of 10 × 100 cm. The layout of system is given. The instrumentation and the interlock system are described. First experiences with this system are presented.},
