1 Nuclear physics and facilities in China Weiping LiuCIAE, China institute of atomic energyIUPAP WG9 symposium, TRIUMF, VancouverJuly 2, 2010只有20分钟，最多25张片子！
2 Facilities in China (Not complete) Nuclear physicsCSR LanzhouHI-13/BRIF BeijingParticle physicsBEPCII BeijingMore can be heard from Prof. Zhan’s talkApplicationSSRF Shanghai, BEPCII Beijing, and USTC Heifei, synchrotron radiation facilitiesCARR and CSNS, neutron facilities
3 Scope of study Nuclear physics with stable nuclei SHEReaction and structureNuclear physics with unstable nucleiReactionStructureNuclear astrophysicsFunded byMOST, 973NSFCCAS, MOE, CAEA, and other fundsSocieties and meetingsNN2009, held in Beijing in August 16-21, 2009China nuclear physics societyExperimentalIMP, CSR, HI physicsCIAE, HI-13, BRIF, low E NPOther: IHEP, SINAP, PKU, USTC and othersTheoreticalAll institutes abovePKU, THU, plus other universities
4 Two major facilities in nuclear physics Beijing BRIF, BRIF II ,Low E HI, RIB, 2013Lanzhou, CSR Med E HI, RIB, 2008
5 Research activities Physics Detector Reaction and others around coulomb in Beijing, few tens MeV A at Lanzhou and RIKENSIAP: Lanzhou exp, for total cross section 23Al, 27P and 17F, Riken exp, 23Al; 2p emission in Lanzhou for CIAEreaction 17F+12C at CNS and near barrier and fusion, in CIAEPKU: 17Ne, 16C Lanzhou, 6He and 8He in RIKEN, transfer and breakupCSR mass measurement in LanzhouDecay, and the PKU for beta-n, 21NIn-beam gamma exp, CIAE, Lanzhou, Jilin, TU, PKU, stale nucleiNuclear astrophysics, indirect and direct and decay, in CIAE, Lanzhou, TRIUMF and CNSSuper heavy elements: mainly performed in Lanzhou1st Observation of antimatter hyper-nucleus: RHIC STAR-SIAPMany theoretical activitiesDetectorGood collaboration in gamma array: Beijing-LanzhouCharged particle array, Lanzhou, CIAE and PKUPKU for beta-n decayNeutron detection wall, Lanzhou and PKUGas fill separator for SHE in Lanzhou

12 BRIF (Beijing rare ion beam facility) 100 MeV 200 mA compact proton cyclotron20000 mass resolution ISOL, 2 MeV/q super-conducting LINACAlready funded, but requiring additional supplementBrief idea in 1990, supported in 2004 Available inCyclotronISOLTandemSCL
14 Project Milestone Original idea in 1990 Evaluation in 1997 Project approved in 2003Feasibility plan approved ($27 M) in 2004First budget ($20 M) come to CIAE in 2005Renewed feasibility plan finished in 2006Revised feasibility plan submitted in 2008Revised feasibility plan got permission in Aug ($52 M)Project design report approved in July 2010Deliver to user in 2013
15 BRIF status in 2010Cyclotron: magnet rough finished, with detailed fabrication finishedISOL: design finished, target-source area in progressSC linac: design finished, all the fabrication in progressCivil engineering will start by the end of the year
20 CARR get its first criticality in May 13! CARR: China Advanced Research ReactorCARR get its first criticality in May 13!可喜的是，我国投巨资建立了CARR研究堆，其主要技术指标和性能已达到国际先进水平。CARR 计划于今年6月装料，9月临界。目前，已经通过各项安全检查，正在等待发放安全许可。power MW flux n/(cm2·s)ＩＬＬ５７１.２ 1014ＣＡＲＲ６０８ l014ＦＲＭ－ＩＩ２０
