  1. Collaboration on synchrotron radiation research 2004/6/17

  2. New beam lines: design and construction • New Wiggler : design • Development of new experimental methods

  3. Lithography VUV Macro-molecular crystallography 3B1A Detector Calibration 3W1A High-pressure diffraction Soft X-ray Optics 3B1B 3W1B 3W1 X-ray Diffraction Small angle scattering 3B3 3B1 BEPC Photoemission Spectroscopy 4B9A 4W2 4B9B Topography 4W1A 4B9 1W1 fluorescence 4W1B 4w1 The Project (in 2000) To construct two multiple-pole Wigglers And three beam lines XAFS Diffuse Scattering

  4. Project in BSRF 2000 • 1. Construct Three beam lines • macro-molecule beam line and end station • XAFS beam line • intermediate energy X ray beam line • Construct two multi-pole Wigglers : • 1W1 ,4W2 3. Upgrade some beam lines in used

  5. 1. The beam lines design and construction • 3W1A Beam line and end station (for macro-molecule crystallography) • 1W1B beam line (For XAFS ) • Front end

  6. Apr. 2000 to discuss the preliminary design report Sheng Weifan ( BSRF deam line reform ) Yang Shishun ( 1W1,4W2: front end design) Xu Zhengan ( 3B3: frond end design ) Liu Peng ( 3W1 ;Micro-molecular crystallography) Xiao Xianghui (1W1B beam line ) Zhu Peiping ( 3B3 beam line )  2000/11 Visited BSRF review technical report Prof. H. Kawata, M. Nomura, Y. Hori, M. Kato

  7. Visited PF July 2001 Sheng Weifan Xiao Xianghui ( 1W1B beam line ) Oct. 2001 Liu Peng ( 3W1 beam line ) Understanding the installation and alignment technologiesused for the undulator beam line at the AR/PF

  8. Focus Collimators Monochromator The main optics and the layout of the beam line 3W1 and 1W1B beam line.

  9. The key point of technique • How to cooling the first crystal of the monochrometor ? • PF: micro channel direct water cooling structure • By using two crystals provided by the PF, the high heat load problem from wiggler sources has been overcome on 3W1 and 1W1B beamlines. • contributed excellent stability to the performance of those two beamlines.

  10. Macro-molecule crystallography Station 3W1A Beam Line 2002/5 Installation 2002/11 Commissioning 2003/1 Opened to Users

  11. offered over 3000 hours experiment time for the users more than 30 groups have made experiments about 200 set of data have been obtained Users have got some important results

  12. SARS coronavirus protein 3CLMpro and its complex with an inhibitor Prof. Z.H. RaoTsinghua university PNAS, vol. 100, 13190 (2003)

  13. Structure of a spinach light-harvester Prof. W.R. Chang (Institute of biology physics) Nature Mar.18, 287, 2004 Data collected at PF and BSRF

  14. March 2003 XAFS beam line Installation Prof. M. Nomura visited BSRF at Jan. 2003 To advise on XAFS beam line installation and adjustment Visit PF Prof. Xie Yaning XAFS experimental station Prof. Dong Yuhui Protein Crystallography

  15. The commissioning work finished at May 2003, hereafter the 1W1B-XAFS beam line begin to accept the proposals form the users

  16. More than 60 groups have made experiments here users are come from different fields

  17. Bio-XAS A Venom Metalloprotein MS Fitting Zn XAFS fine structure
