Path to NSLS-II• Feb. 25-26, 2006 “NSLS X-Ray High Pressure Research Workshop:

Current operation and vision into NSLS II”Report prepared by J. Chen et al.

• July 17-18, 2007 High-pressure discussion session at “NSLS-II Users Workshop”. “High Pressure Needs at NSLS-II Synchrotron” prepared by D. Weidner et al.

• January 17-18, 2008 “Materials at High Pressure” breakout session during the Workshop on “The NSLS-II Powder Diffraction Project Beamline” and “Materials Science Engineering Strategic Planning for NSLS and NSLS-II. White paper prepared by Lars Ehm et al. http://www.compres.stonybrook.edu/Workshops/index.html

• May 21, 2008 “Future Directions in High Pressure Research” with discussion session on NSLS-II, Workshop at NSLS/CFN user meeting (sponsored by COMPRES and NSLS/CFN)

High Pressure Program• Dedicated Beamlines

– High-energy superconducting wiggler beamline with 4 endstations (HiPHEX)

• Letter of Interest submitted March 2008– Intermediate energy beamline at U20 source– IR spectroscopy beamline

• High Pressure Capabilities– IXS, PING, XAS project beamline– Material science beamlines– Earth sciences beamlines

• Integrated High Pressure Philosophy– NSLS-II extreme conditions laboratory

• Seed for high pressure research around the ring– Integration of BNL/CFN infrastructure in post experiment

sample characterization

What’s next• Decision on project beamlines (June

2008)– Feedback on the HiPHEX LOI

• Next LOI due end of August 2008– U20 (Champion: Viktor Struzhkin (CIW))– IR move

• November 2008 NSLS-II expects CD-3– Defining final source properties, lattice

etc.
