During the experiment, the photon flux at the Surface Diffraction Beamline (BL02U2) of the Shanghai Synchrotron Radiation Facility exhibited a gradual attenuation phenomenon, which severely impacted the progress of scientific experiments. At 8 keV, the photon flux decreased by 20% over a period of 20 hours; whereas at 19 keV, the photon flux dropped by 78% within just 20 minutes. To address...

Contributed Oral Presentation

We present an active cooling system for the grating mirrors of ID32 soft X-ray beamline at the European Synchrotron Radiation Facility (ESRF). The design combines flexible copper braids to minimize mechanical stress in the grating mirrors with active temperature control to accelerate thermal response. Development followed a model-based approach, integrating dynamic Simulink thermal simulations...

Contributed Oral Presentation

SAPOTI is the second nanoprobe at the CARNAÚBA (Coherent X-Ray Nanoprobe Beamline) beamline at the 4th-generation light source Sirius/LNLS. Working from 2.05 to 15 keV, it relies on simultaneous multi-analytical X-ray techniques (absorption, diffraction, spectroscopy, fluorescence and luminescence) and imaging in 2D and 3D. It has been designed for highly-stable fully-coherent beam sizes from...

5. Recent advances in X-ray microscopy instrumentation developments at NSLS-II (TUOB04)

End Stations

Contributed Oral Presentation

X-ray microscopy is a mature characterization tool routinely used to investigate diverse material questions of science, technology, and engineering. The high penetration power of X-rays allows the utilization of different characterization methods and reveals elemental composition, crystalline phases, strain distribution, oxidation states, etc. in macroscopic and microscopic samples. ...

104. Development of a Coherent Diffractive Imaging (CDI) Endstation at the SPring-8 II 12XU (TUOB05)

Contributed Oral Presentation

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...
