A Brighter Infrared Beamline

Upton, N.Y., 8 March 2011- The conceptual design will go forward for a new infrared beamline spearheaded by the Geophysical Laboratory and dedicated to high-pressure science at NSLS II.

Zhenxian Liu of the Geophysical Laboratory, who directs the high-pressure IR program at NSLS, received this news about the proposed beamline  which is called the Frontier Synchrotron Infrared Spectroscopy Beamline under Extreme Conditions (FIS) at the NSLS-II facility under construction at the Brookhaven National Laboratory.

In an announcement from Dr. Steve Dierker, Associate Laboratory Director for Light Sources and NSLS-II, Zhenxian Liu has been asked to oversee a Beamline Advisory Team (BAT) as part of the possible new construction for this beamline. The announcement went on to say that it was decided to allocate funds toward the development of a conceptual design for the 16 approved beamlines.  The FIS beamline is one of the 16 approved beamlines that will involve infrared spectroscopy utilizing bending magnet sources for experiments under extreme conditions. The BAT will provide oversight for the development of the beamline and will ensure that the conceptual designs will fulfill the demands of the growing high-pressure user community.

Infrared synchrotron radiation sources provide well-collimated beams from far-to-near-IR that give high spatial resolution with unmatched signal-to-noise. High-pressure synchrotron IR spectromicroscopy represents an ideal coupling of diamond anvil cells and IR radiation. The Geophysical Laboratory, which operates the U2A IR beamline at NSLS (NSLS-U2A), has been taking the leading role in developing new techniques for high-pressure IR spectroscopy with synchrotron radiation for more than two decades. Recent major beamline upgrades/developments including the construction of the U2A side station and a CO2 laser heating system which will position the program well for the transition from NSLS to NSLS-II.  The proposed large-gap dipole IR port for the FIS beamline will provide unparalleled brightness and exceptional stability/low noise in the entire IR spectral region for spectroscopic studies under extreme conditions such as static and dynamic compression and variable temperatures.
