Igor Zaliznyak, right, and David Forbes, both of Brookhaven National Laboratory, are among the early users doing experiments at the HYSPEC instrument at the Spallation Neutron Source.

A new research instrument, the Hybrid Spectrometer (HYPSPEC), is online at the Spallation Neutron Source (at Beam Line 14-B) and being commissioned for experimental use. According to infor released by Oak Ridge National Laboratory, the new instrument "combines the time-of-flight technique used at pulsed sources such as SNS with the advantages of crystal spectrometers that use continuous neutrons,:"

ORNL spokesman Bill Cabage said HYSPEC was developed by a team that included participation from top U.S. universities, as well as national labs and an international user group. "HYSPEC is a new concept in high-flux inelastic neutron spectrometry," he said.

Cabage said HYSPEC is the first polarized beam spectrometer among the SNS research instruments.

A dozen instruments have already been commissioned at the SNS, which sits atop Chestnut Ridge about a mile from the main ORNL campus, and HYSPEC and another newcomer, TOPAZ, a single crystal diffractometer, are being commissioned for experimental use.

ORNL said HYSPEC is used to studying single-crystal samples and investigating the "low-energy, atomic-scale dynamical properties of crystalline solids."

Barry Winn and Mark Lumsden are the instrument scientists, the lab said. Besides Winn and Lumsden, the team working with eary users on HYSPEC includes Melissa Graves-Brook, Mark Hagen, and Andrei Savici.
