  1. Nuclear physics and facilities in China Weiping Liu CIAE, China institute of atomic energy IUPAP WG9 symposium, TRIUMF, Vancouver July 2, 2010

  2. Facilities in China(Not complete) • Nuclear physics • CSR Lanzhou • HI-13/BRIF Beijing • Particle physics • BEPCII Beijing • More can be heard from Prof. Zhan’s talk • Application • SSRF Shanghai, BEPCII Beijing, and USTC Heifei, synchrotron radiation facilities • CARR and CSNS, neutron facilities

  3. Scope of study • Nuclear physics with stable nuclei • SHE • Reaction and structure • Nuclear physics with unstable nuclei • Reaction • Structure • Nuclear astrophysics • Funded by • MOST, 973 • NSFC • CAS, MOE, CAEA, and other funds • Societies and meetings • NN2009, held in Beijing in August 16-21, 2009 • China nuclear physics society • Experimental • IMP, CSR, HI physics • CIAE, HI-13, BRIF, low E NP • Other: IHEP, SINAP, PKU, USTC and others • Theoretical • All institutes above • PKU, THU, plus other universities

  8. CSR in Lanzhou

  9. N ECR: keV SFC: 10 AMeV (H.I.),17~35 MeV (p) SSC:100 AMeV (H.I.), 110 MeV (p) CSRm:1000 AMeV (H.I.), 2.8 GeV (p) SSC SFC CSRe ECR RIBLL2 RIBLL1 CSRm RIBLL1: tensAMeV (RIBs) RIBLL2: hundreds AMeV (RIBs & HCI) Introduction to HIRFL HIRFL: Heavy Ion Research Facilities in Lanzhou Stable Beams Radioactive Beams

  10. History of CSR 1993 Original idea 1996 Proposal 1998 Approved 2000-2005 Construction 2006-2007 Commissioning 2008-2009 Operation & Experiments

  11. BRIF in Beijing

  12. ISOL Cyclotron Tandem SCL BRIF(Beijing rare ion beam facility) 100 MeV 200 mA compact proton cyclotron 20000 mass resolution ISOL, 2 MeV/q super-conducting LINAC Already funded, but requiring additional supplement Brief idea in 1990, supported in 2004 Available in 2011-2012

  13. RIB intensity expected

  14. Project Milestone • Original idea in 1990 • Evaluation in 1997 • Project approved in 2003 • Feasibility plan approved ($27 M) in 2004 • First budget ($20 M) come to CIAE in 2005 • Renewed feasibility plan finished in 2006 • Revised feasibility plan submitted in 2008 • Revised feasibility plan got permission in Aug. 2009 ($52 M) • Project design report approved in July 2010 • Deliver to user in 2013

  15. BRIF status in 2010 • Cyclotron: magnet rough finished, with detailed fabrication finished • ISOL: design finished, target-source area in progress • SC linac: design finished, all the fabrication in progress • Civil engineering will start by the end of the year

  16. Engineering layout

  17. 3D internal structure of proton cyclotron

  18. Magnet design and fabrication

  19. CARR and CSNS

  20. CARR: China Advanced Research Reactor CARR get its first criticality in May 13!

  21. Neutron physics: Neutron scattering Residual stress diffractometer cooperated with Switzerland

  22. CSNS in Guangdong
