"New Frontier in High-Pressure Research at the NSLS-II"

Thomas S. Duffy, Princeton University

NSLS-II is a proposed new storage ring at Brookhaven National Laboratory that will deliver x-rays with 10⁴ times the brightness of the current NSLS.  Design and engineering of the new light source began in 2007 and construction and operations are expected to begin in 2009 and 2015, respectively. For high-pressure research, the NSLS-II x-ray sources promise substantial improvements over existing NSLS beamlines.  These advantages arise from the following four factors: reduction in storage ring emittance (yielding smaller source size and divergence), increased allowed length of insertion devices, increased ring current, and increased ring energy.  The current NSLS will decommissioned after the NSLS-II becomes operational.

A proposed suite of high-pressure beamlines and facilities are being proposed for the NSLS-II.   These include dedicated wiggler, undulator, and infrared beamlines as well as incorporation of high-pressure activities at more specialized beamlines around the ring.  The proposed superconducting wiggler beamline will include primary stations dedicated to large-volume press and diamond anvil experiments as well as two fixed-energy side stations. State-of-the-art high-pressure laboratory facilities will also be included in the design.

This talk will discuss the scientific opportunities for high-pressure and deep Earth research afforded by the new capabilities of NSLS-II.   The current status of proposals for high-pressure beamlines and integrated high-pressure research activities will be presented.  Members of the high-pressure community are encouraged to become involved in the planning and design of this major new research facility.
