  1. C.E.G.O.China Einstein Gravitational wave Observatory R. DeSalvo G040121-00-0

  2. China has a long history of interest in the Universe 7-4-1054 700 b.C. And two GW bars, Beijing and Guandong G040121-00-0

  3. How did it happen • In 2003 Wang Yunyong, visitor at Livingston got interested in GW detection • Getting time to leave, looking for a way to continue, contacts Tang Keyun of Geophysics Institute of Beijing • Tang Keyun proposes to Academia Sinica the idea of a Chinese group at LSC • Instead of forming a group to join LSC, they are invited to propose a Chinese interferometer ! ! G040121-00-0

  4. How did it happen • Coming from Geophysics, they decide to propose an underground facility • On Christmas eve they contact me, ask to come to LIGO to present the idea • January 12th Wang and Tang in Caltech • Tang gives a LIGO talk presentingCEGO • For funding they need an original idea, somewhat different from what done elsewhere • It is decided that the underground facility will concentrate towards Low Frequency GW sensitivity G040121-00-0

  5. C.E.G.O. kickoff workshop • Kickoff workshop organized in Beijing, March 1-3 • The workshop starts with the support letters from GWIC, LIGO, Virgo and TAMA • 70 scientist and 20 institutions participate, including representatives from GWIC, LIGO, Virgo and TAMA, at the presence of a Science Ministry representative • Academia Sinica, NSF-C, NAO-C pledge support for the initiative for a three year starting period G040121-00-0

  6. The first C.E.G.O. workshop G040121-00-0

  7. What’s next • March 3rd, National Astronomical Observatory-C hosts the initiative, hiring Tang off Geophysics • NAOC will provide premises and staff to organize a mid size test interferometer and prepare a proposal for a full facility in three years • March15th, first seed funding from NAOC • Additional interim funding expected to come from Academia Sinica and NSFC (~> 10 MY ?) • March 30th presentation of three-year proposal to the ministry for developmental funding G040121-00-0

  8. What’s next • In LIGO we will apply for an NSF grant to support the initiative • A larger, international workshop will be organized under the GWIC auspices • Chinese visitors to LIGO, Virgo and TAMA to practice with real interferometers (1-2 years) • Design and build test interferometer in Beijing • Choose site, design new interferometer, …… G040121-00-0
