Experimental Setup Design of Hard X-ray Coherent Scattering (HXCS) Beamline at HEPS | |
|
||
| The HXCS is a dedicated coherent beamline of the High Energy Photon Source (HEPS). The experimental setup of the endstation mainly includes two devices: CDI/WAXS XPCS and SAXS XPCS. To achieve high stability requirements, the CDI/WAXS XPCS device use a nano-focusing AKB mirrors system, which will focus hard x-rays to a focal spot as small as 100 nm with a small working distance of 64 mm. In the narrow working distance, AKB mirror chamber and sample chamber are designed as a unit but separated from the middle. And the device is designed with two sets of switchable sample table, in order to flexibly carry out four coherent techniques. Due to high stability, the CDI/WAXS XPCS device is stringent designed for high stiffness, high temperature stability and metrology. Besides, the other important equipments of the beamline include a 1.5m WAXS tube and a 14m SAXS tube. For high-resolution applications, the WAXS tube can be rotated around the sample in the horizontal and vertical plane by 45°and the SAXS tube can adjust distance and angulation. At present, the whole experimental setup is designed according to the fine mechanical design which can meet the experimental requirements. | ||
