Pfeffer, S.P. JACoW Publishing Geneva, Switzerland The SAXSMAT Beamline P62 at PETRA III (DESY) can perform small- and wide-angle X-ray scattering simultaneously. The SAXS instrument is based on a tube system with SAXS detector inside under high vacuum conditions (~ 10⁻⁵ mbar). The tube system is 13m long with a diameter of 1m. The tube system allows continuous movement of the detector along the beam direction and is made possible by means of a rack and pinion drive. The distance of the detector can be changed without breaking the vacuum, resulting in time savings during operation. The vacuum compatible detector can moved over a travel range of 12m. The two motors are water-cooled with a simple pipe coil of copper. All cables and cooling pipes will be moved with the help of a counter rotating drag chain, made by stainless steal.
