Double-focusing small-angle x-ray scattering camera at an ESRF undulator

Abstract
A double‐focusing small‐angle x‐ray scattering camera has been installed at the European Synchrotron Radiation Facility. The camera uses a low‐β undulator as insertion device. Stable operation has been demonstrated at 13 keV. A beam size at the sample position in the range of 100–200 μm and a flux in excess of 1010 Ph/s have been obtained. The camera allows to resolve the first order of collagen (67 nm).
