The spin-echo spectrometer at the Spallation Neutron Source (SNS)

• A novel neutron spin-echo spectrometer with superconducting main coils enabling enclosure by a double walled mu-metal magnetic shielding chamber has been built and set into operation at the spallation neutron source in Oak Ridge. The layout of the spectrometer is described. Performance with emphasis on the superconducting main solenoids and the time-of-flight operation is described. Data on resolution, stability and first experiments are shown. (C) 2012 Elsevier B.V. All rights reserved.
