  2. 1、Introduction Short story • In April, 1995, the CAS and SMG agreed in principle to make joint efforts for a proposal to construct the SSRF in Shanghai. • In June, 1995, a working group to carry out the feasibility study of the SSRF was set up by the CAS. • In 1995, project team (then called working group) started holding the symposiums to discuss what the users need and which kind of beamline the first group should contain ( over 100 users from about 50 universities, institutes and companies). Shanghai Synchrotron Radiation Facility SSRF

  3. Requiements and suggestions • SSRF should be a advanced third generation synchrotron radiation facility. • SSRF should be a user's facility (alignment with user's requirements and needs). • Their shold be enough (?) beamlines meet requirements and needs of users. Beamline allocation models cover the spectrum from FOOB's to PRT/CAT's . Shanghai Synchrotron Radiation Facility SSRF

  4. The research lifetime must be longer than 20-30 years after its establishment. • Proposed rules for choosing first group beamlines  Advanced beanline --- tomorrow  Popular beamline --- today Social impact and industry application Shanghai Synchrotron Radiation Facility SSRF

  5. Soliciting the proposals • In March, 1996, Working group sent out a anouncement to 58 universities and institutes all over China to solicit the proposals of first group beamlines of SSRF. • Announcement (in Chinese). • The fifteen beamnlines were proposed as candidates (Table 1). • Only 5 to 7 beamlines (including 2-3 insertion devices) will be constructed in the first phase of construction.

  6. Announcement for Soliciting Proposal of Beamlines and Design March 1996 Shanghai Synchrotron Radiation Facility SSRF

  7. Proposal Beamlines to users for Soliciting Design March 1996 Shanghai Synchrotron Radiation Facility SSRF

  8. By the end of 1997, Around 70 proposal came from more than 20 Universities And Institutes. • The proposals receivedwere concerned with seventeen beamlines. • Distribution of the proposed beamlines Shanghai Synchrotron Radiation Facility SSRF

  12. …… Important scientific issuses which require UV radiation have decreased in number compared to those which require hard x-rays ( Birgenau-Shen's Report, 1997). • New tendency: use of coherence/ Micro focus for hard x-ray / Inelastic scattering / Molecular Environment Science (MES) /Infrared---. • Energy of SSRF storage will increase to 3.5 Gev from (2.2 -2.5) GeV in 1998. Shanghai Synchrotron Radiation Facility SSRF

  13. Dec.24-25, 1998, a symposium was held to discuss the proposals received, about 130 users who submitted proposals attended the symposium. • Based on the through discussion in the symposium, the Science and Technology Committee (STC) of SSRF chose seven plus one from twenty one beamlines proposed (four more proposals) as the first group beamlines.
