At SPring-8, several new beamlines are currently under construction and additional beamlines are also being considered for construction. The beamlines at the SPring-8 Facility are categorized into three types: - Public beamlines, constructed by SPring-8, open for public use. This category includes the R&D beamlines. - JAERI / RIKEN beamlines, constructed by JAERI / RIKEN for their exclusive use. - Contract beamlines, constructed by universities, institutions or industries for their exclusive use. By the end of 2000, twenty-one public beamlines were operational and available for public use: BL01B1 XAFS BL02B1 Crystal Structure Analysis BL02B2 Powder Diffraction BL04B1 High-Temperature Research BL04B2 High Energy Monochromatic X-ray Studies BL08W High Energy Inelastic Scattering BL09XU Nuclear Resonant Scattering BL10XU Extremely Dense State Research BL20B2 Medical and Imaging Application I BL25SU Soft X-ray Spectroscopy of Solids BL27SU Soft X-ray Photochemistry BL28B2 White Beam Topography BL35XU High-Energy Resolution Inelastic Scattering BL38B1 R&D(3) (bending magnet beamline) BL39XU Magnetic Materials BL40XU High Flux BL40B2 Structural Biology II BL41XU Structural Biology I BL43IR Infrared Materials Science BL46XU R&D (2) (short period in-vacuum type undulator) BL47XU R&D (1) (standard in-vacuum type undulator) As of 2000, the following beamlines are nearly completed and will soon be ready for public use: BL13XU Surface and Interface Structures BL19B2 Engineering Science Research BL20XU Medical and Imaging Application II BL37XU Trace Element Analysis Of these, BL13XU, BL19B2 and BL20XU will be commissioned in April, 2001, including some public use trial. The BL37XU beamline will follow shortly after the commission of these three beamlines. Ten beamlines have been constructed / are under construction by JAERI and RIKEN for the exclusive use of JAERI and RIKEN scientists: BL11XU Materials Science II ( JAERI ) BL14B1 Materials Science I ( JAERI ) BL19LXU Synchrotron Radiation Physics Studies (RIKEN) BL22XU Materials Science III ( JAERI ) BL23SU Actinide Studies by Soft X-rays (JAERI) BL26B1 Structural Genomics I (RIKEN) BL26B2 Structural Genomics II (RIKEN) BL29XU Coherent X-ray Optics (RIKEN) BL44B2 Structural Biology II (RIKEN) BL45XU Structural Biology I (RIKEN) BL19LXU is a 30 m-long straight section beamline and the long undulator was installed after t h e r e a r r a n g e m e n t o f t h e m a g n e t s i n t h e s t o r a g e r i n g d u r i n g t h e s u m m e r o f 2 0 0 0 .

BL29XU has two experimental stations, one at the standard length of 80 m, and the other located at 1,000 m from the undulator source. Tatzuo Ueki SPring-8 / JASRI Eight contract beamlines at SPring-8 are either in operation or under construction. BL12IN APCST ID beamline (Taiwan) BL12B2 APCST BM beamline (Taiwan) BL15IN Materials Science ( National Institute for Research in Inorganic Materials) s BL16XU Materials Science (Industrial Consortium) BL16B2 Materials Science (Industrial Consortium) BL24XU Multi-purpose ( Hyogo Prefecture) BL33LEP Laser Electron Photon Studies ( Osaka University) BL44XU Macromolecular Assemblies ( Osaka University) All beamlines are shown in the Beamline Map. We have two beamlines, a contract beamline ( B L 3 2 B 2 ) f o r P h a r m a c e u t i c a l C o n s o r t i u m , t o b e c o m p l e t e d b y t h e e n d o f 2 0 0 1 , a n d a R I K E N bea mli ne ( BL1 7SU ) for sof t X-r ay spe ctr osc opy , the con str uct ion of whi ch wil l beg in in FY2 001 . The latter is positioned as an R&D beamline for ultra-high brilliance soft X-ray spectroscopy. These two beamlines are not included in the Map. Including the two accelerator diagnosis beamlines, we have forty seven beamlines, i.e. , more than 3/4 beamlines of sixty-two beamlines possible at SPring-8.
