Status of the crystallography beamlines at SSRF
The European Physical Journal Plus, 2015The Shanghai Synchrotron Radiation Facility (SSRF), an advanced intermediate-energy third-generation light source in China, was completed with seven phase-I beamlines opening to users in May 2009. Among these beamlines, there are two dedicated crystallography beamlines, one for macromolecular crystallography and one for crystallography in materials ...

Soft X-ray ptychography method at SSRF
Nuclear Science and Techniques, 2017Ptychography is a diffraction-based X-ray microscopy technique in which an extended sample is scanned by a coherent beam with overlapped illuminated areas and complex transmission function of the sample is obtained by applying iterative phase retrieval algorithms to the diffraction patterns recorded at each scanned position.

First Group of Insertion Devices for SSRF
AIP Conference Proceedings, 2007Shanghai Synchrotron Radiation Facility (SSRF) is an intermediate energy (3.5GeV) light source under construction. Seven beamlines have been chosen and five IDs will be built in the first stage. Two wigglers used for X‐ray absorption fine structure (XAFS) and X‐ray imaging (XI), two in‐vacuums undulators used for macromolecular crystallography (MC) and

Suppression of Ground Vibration for SSRF Foundation
Applied Mechanics and Materials, 2011The electron beam stability is one of the most important requirements for the Shanghai Synchrotron Radiation Facility (SSRF), whose ground vibration is much larger than other light source for softer soil and deeper rock. This paper concentrates on the attenuation of the ground vibration, especially induced by the nearby vehicles.

Filling Pattern Measurement System Upgrade in SSRF*
2018Filling pattern affects various operation performance of a synchrotron light source. A new diagnostic beam charge monitor (BCM) with high bandwidth multi-channels digitizer was developed to perform bunch-by-bunch charge measurement and record filling pattern for SSRF storage ring.

The dynamic micro computed tomography at SSRF
Journal of Instrumentation, 2018Synchrotron radiation micro-computed tomography (SR-μCT) is a critical technique for quantitative characterizing the 3D internal structure of samples, recently the dynamic SR-μCT has been attracting vast attention since it can evaluate the three-dimensional structure evolution of a sample. A dynamic μCT method, which is based on monochromatic beam, was
