The holographic x-ray scattering chamber (Holographische Röntgenstreukammer HORST) is a new experimental station for coherent x-ray sources such as synchrotrons and free electron lasers. It is designed for digital in line holography but also flexible to have add ons like magnets or beamstops for diffraction imaging. HORST consists of a large vacuum chamber with three stage systems for pinhole, sample and camera positioning and a differential pumping stage to achieve a very good vacuum pressure at the beamline. All this is mounted on a mobile and height adjustable framework. The three motorized stage systems has 13 axes of motion: pinholes can be moved and tilted perpendicular to the beam axis, samples can be moved in all three dimensions as well as rotated for tomography and the CCD camera can be positioned. We present first images acquired at UE52SGM at BESSY which characterizes the imaging properties of the system. The applicability to handle biological samples and first holotomography results will be presented.
