Cold Neutron Chopper Spectrometer (CNCS)
The Cold Neutron Chopper Spectrometer (CNCS), on beam line 5, is a high-resolution, direct-geometry, multi-chopper inelastic spectrometer designed to provide flexibility in the choice of energy resolution and to perform best at low incident energies (2 to 50 meV). Initially, the detector coverage around the sample is 1 sr, but a later upgrade to 3 sr is possible. Experiments at CNCS typically use energy resolutions between 10 and 500 ยตeV. A broad variety of scientific problems, ranging from complex and quantum fluids to magnetism and chemical spectroscopy, are being addressed through experiments at CNCS.
A University-National Laboratory collaboration funded and oversaw development of this instrument. This CNCS Instrument Development Team (IDT) is lead by Pennsylvania State University. Primary members are MIT and the universities of Michigan, Berkeley, and Missouri. Additional information is provided on the IDT web site, from spokesperson Paul Sokol, or the lead instrument scientist, Georg Ehlers.
