  1. Multi-Anvil at X17B2 of the NSLS Donald Weidner (Jiuhua Chen)

  2. NSLS delivered beamtime NSLS Activity Report 2004

  3. X17B3 X17B2 X17B1 NSLS delivered beamtime: 4725 hours = 197 days X17 beamtime distribution: X17B2 designated beamtime: 49.2 days

  4. Beamtime Usage of X17B2

  5. White beam

  6. Implement of remote operation Enhance beamtime sharing abilities (Facility Development) Decrease beam interruption time between experiments. Before: ~ 40min After: ~ 4min

  7. NSLS EDXD with SSD ADXD with CCD ADXD with IP X-ray radiograph Acoustic velocity High Pressure in situ Measurements using X-rays HP cell

  8. Research Capabilities • Phase relation at high P/T (phase diagram) • P-V-T equation of state • Crystal structure • Melt density and viscosity • Sound velocity • Rheology (D-DIA) • Rheology (RDC–Yale group)

  9. Beam entrance from X17B1 Focusing Si(331) Pass through beam for X17B3 X17B2 main station beam Nonfocusing Si(331) White beam NSLS contribution (optics component – monochromator) MAR 345 detector: November 2004 Mono beam Facility Development Monochromatic side station Funding (DOD + SB matching) 2004 June

  10. Challenging higher pressures in multi-anvil press New Initiative Existing effort: Stony Brook, Geophysical Lab, APS

  11. Proposal for Partnership for Geophysical High Pressure Research (Submitted to NSFOISE) • challenging higher achievable pressure using sintered diamond • study of melts property at high pressures List of Participants US:Japan: Jiuhua ChenYingwei Fei Ken-ichi Funakoshi Shun-ichi KaratoJie Li Eiji Ito Baosheng LiJohn B.
