CSR in Lanzhou

Introduction to HIRFL HIRFL: Heavy Ion Research Facilities in Lanzhou CSRm CSRe SFC SSC 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) RIBLL1: tens AMeV (RIBs) RIBLL2: hundreds AMeV (RIBs & HCI) RIBLL2 RIBLL1 ECR Stable Beams Radioactive Beams

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

BRIF in Beijing

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 Cyclotron ISOL Tandem SCL

RIB intensity expected

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

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
