Abstract： The X-ray diffraction beamline developed at Shanghai Synchrotron Radiation Facility (SSRF)is located at the BL14B1 bending magnet port of the 3.5 GeV storage ring. The beamline optics is based on a collimating mirror, a sagittally focused double crystal monochromator and a focusing mirror. Photon flux of 4.43�1011 phs/s at 10 keV is obtained. The primary instrument equipped in the experimental end-station is a Huber 5021 six-cycle diffractometer. BL14B1 is a general purpose X-ray diffraction beamline and focused on material science, condensed matter physics and other relevant fields looking for structural information.

Abstract： The control system of SSRF (Shanghai Synchrotron Radiation Facility) is based on EPICS (Experimental Physics and Industrial Control System). Operation data storage for synchrotron radiation facility is important for its status monitoring and analysis. At SSRF, operation data used to be index files recorded by traditional EPICS Channel Archiver. Nevertheless, index files are not suitable for long-term maintenance and difficult for data analysis. Now, RDB Channel Archiver and MySQL are used for SSRF beamline operation data archiving, so as to promote the data storage reliability and usability. By applying a new uploading mechanism to RDB Channel Archiver, its writing performance is improved. A web-based GUI (Graphics User Interface) is also developed to make it easier to access database.
