Cold Neutron Chopper Spectrometer at SNS. Click image for a larger view.
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 (2-50 meV). Initially, the detector coverage around the sample is 1 sr, but a later upgrade to 3 sr is possible. CNCS experiments will typically use energy resolution between 10 and 500 µeV. A broad variety of scientific problems, ranging from complex and quantum fluids to magnetism and chemical spectroscopy, will be addressed through experiments on CNCS at SNS.
A University-National Laboratory collaboration has stepped forward to fund and oversee the development of this instrument. This Instrument Development Team (IDT) is lead by The Pennsylvania State University and the primary members are MIT, and the Universities of Michigan, Berkeley, and Missouri. Currently a detailed design, optimized for the diverse science planned by the IDT, is in progress. Additional information is provided on the IDT website, http://www.cncs.iucf.indiana.edu/cncs/, from their spokesperson,

Recent Significant Events:
The secondary spectrometer will be housed in a satellite building. The construction of this building has been finished.
Key components, such as the neutron guide and the high-speed choppers, have been received, or are expected to arrive at SNS later in 2007.
