  • Beijing Synchrotron Radiation Facility
    Review of Scientific Instruments, 1995
    Co-Authors: Xiaoming Jiang, Esheng Tang, Dingchang Xian
    Abstract:

    The storage ring for the Beijing Synchrotron Radiation Facility (BSRF) is the 1.6–2.8 GeV Beijing Electron‐Positron Collider, which was constructed for China’s first project on high‐energy physics research. The storage ring was designed to be operating either in the colliding mode or in the dedicated synchrotron‐Radiation mode. The project was approved by the Chinese government at the end of 1983, and was completed in 1989. The Beijing Synchrotron Radiation Laboratory was founded in July of 1985, and the construction of the first beam line was completed in 1989. The first phase construction of BSRF was finished in 1991; three beam ports, seven beam lines, and nine experimental stations were constructed. Since 1991, BSRF has been opened to users from all over the country. The description of the beam lines and experimental stations and present research activities is given in this paper. The second phase construction of BSRF as well as the plan of constructing a third‐generation new synchrotron‐Radiation sou...

  • The status of the first infrared beamline at Shanghai Synchrotron Radiation Facility
    Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 2015
    Co-Authors: Te Ji, Tiqiao Xiao, Yajun Tong, Zengyan Zhang, Weiwei Peng, Min Chen, Hongjie Xu
    Abstract:

    Construction of the first infrared beamline BL01B1 at Shanghai Synchrotron Radiation Facility (SSRF) was completed at the end of 2013. The IR beamline collects both edge Radiation (ER) and bending magnet Radiation (BMR) from a port, providing a solid angle of 40 mrad and 20 mrad in the horizontal and vertical directions, respectively. The optical layout of the infrared beamline and the design of the extraction mirror are described in this paper. A calculation of the beam propagation has been used to optimize the parameters of the optical components. The photon flux and spatial resolution have been measured at the end station, and the experimental results are in good agreement with the theoretical calculation. (C) 2015 Elsevier B.V.

  • x ray grating interferometer for biomedical imaging applications at shanghai synchrotron Radiation Facility
    Journal of Synchrotron Radiation, 2012
    Co-Authors: Yan Xi, Juncheng Qi, Jürgen Mohr, Martin Börner, Jun Zhao, Lisa X. Xu, Tiqiao Xiao, Yujie Wang
    Abstract:

    An X-ray grating interferometer was installed at the BL13W beamline of Shanghai Synchrotron Radiation Facility (SSRF) for biomedical imaging applications. Compared with imaging results from conventional absorption-based micro-computed tomography, this set-up has shown much better soft tissue imaging capability. In particular, using the set-up, the carotid artery and the carotid vein in a formalin-fixed mouse can be visualized in situ without contrast agents, paving the way for future applications in cancer angiography studies. The overall results have demonstrated the broad prospects of the existing set-up for biomedical imaging applications at SSRF.

  • The recent development of an X-ray grating interferometer at Shanghai Synchrotron Radiation Facility
    2012
    Co-Authors: Yan Xi, Juncheng Qi, Jürgen Mohr, Martin Börner, Jun Zhao, Lisa X. Xu, Tiqiao Xiao
    Abstract:

    An X-ray grating interferometer has been installed at Shanghai Synchrotron Radiation Facility (SSRF). Three sets of phase gratings were designed to cover the wide X-ray energy range needed for biological and soft material imaging capabilities. The performance of the grating interferometer has been evaluated by a tomography study of a PMMA particle packing and a new born mouse chest. In the mouse chest study, the carotid artery and carotid vein inside the mouse can be identified in situ without contrast agents.

  • Diffraction anomalous fine-structure spectroscopy at beamline BM2 at the European Synchrotron Radiation Facility.
    Journal of Synchrotron Radiation, 2003
    Co-Authors: Hubert Renevier, S. Grenier, S. Arnaud, Jean-françois Berar, B. Caillot, Jean-louis Hodeau, A. Letoublon, M. G. Proietti, Bruce Ravel
    Abstract:

    Diffraction anomalous fine-structure (DAFS) spectroscopy uses resonant elastic X-rays scattering as an atomic, shell and site-selective probe that provides information on the electronic structure and the local atomic environment as well as on the long-range-ordered crystallographic structure. A DAFS experiment consists of measuring the Bragg peak intensities as a function of the energy of the incoming X-ray beam. The French CRG (Collaborative Research Group) beamline BM2-D2AM (Diffraction Diffusion Anomale Multi-longueurs d'Onde) at the ESRF (European Synchrotron Radiation Facility) has developed a state-of-the-art energy scan diffraction set-up. In this article the requirements for obtaining reliable DAFS data are presented and recent technical achievements are reported.
