Description

The National Synchrotron Radiation Research Center operates two beamlines, 12B2 and 12XU, at the Super Photon ring-8 GeV. The SPring-8 II significant improvements in beam properties such as coherence, stability, and intensity are expected. NSRRC has initiated the construction of a Coherent Diffractive Imaging endstation on beamline 12XU. This endstation consists of two main subsystems: zone plate-based X-ray microscope and detector assembly. The microscope is mounted on a granite base to ensure mechanical stability and to minimize vibrational and thermal disturbances. The zone plate-based microscope comprises beam stopper, zone plate optic, optical stop aperture, and sample positioning stage. Each module is equipped with an independent XYZ piezo-driven translation stage. To further mitigate thermal drift and ensure dimensional stability, the stage bases are constructed from Invar alloy, which offers low thermal expansion characteristics critical to maintaining optical alignment over extended experimental durations. The detector system is mounted on a precision linear guideway allowing for fine adjustments of the distance to optimize image resolution and experimental flexibility.
