The new cold neutron chopper spectrometer at the Spallation Neutron Source: design and performance.
The design and performance of the new cold neutron chopper spectrometer (CNCS) at the Spallation Neutron Source in Oak Ridge are described. CNCS is a direct-geometry inelastic time-of-flight spectrometer, designed essentially to cover the same energy and momentum transfer ranges as IN5 at ILL, LET at ISIS, DCS at NIST, TOFTOF at FRM-II, AMATERAS at J-PARC, PHAROS at LANSCE, and NEAT at HZB, at ...
متن کاملNeutron Imaging at Spallation Neutron Sources
Neutron imaging is a powerful method for non-destructive investigations where the high penetration through metals and the high contrast for hydrogenous materials is exploited in particular. The complementary to X-ray studies is a clever alternative in many cases of scientific and industrial applications. Reactor based neutron sources are becoming less available, caused by the shutdown of aged f...
متن کاملThe Fundamental Neutron Physics Beamline at the Spallation Neutron Source
The Spallation Neutron Source (SNS), currently under construction at Oak Ridge National Laboratory with an anticipated start-up in early 2006, will provide the most intense pulsed beams of cold neutrons in the world. At a projected power of 1.4 MW, the time averaged fluxes and fluences of the SNS will approach those of high flux reactors. One of the flight paths on the cold, coupled moderator w...
متن کاملDesign and operation of the wide angular-range chopper spectrometer ARCS at the Spallation Neutron Source.
The wide angular-range chopper spectrometer ARCS at the Spallation Neutron Source (SNS) is optimized to provide a high neutron flux at the sample position with a large solid angle of detector coverage. The instrument incorporates modern neutron instrumentation, such as an elliptically focused neutron guide, high speed magnetic bearing choppers, and a massive array of (3)He linear position sensi...
متن کاملAtomic pair distribution function analysis from the ARCS chopper spectrometer at the Spallation Neutron Source
Neutron powder diffraction based atomic pair distribution functions (PDFs) are reported from the new wide angular-range chopper spectrometer ARCS at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL). The spectrometer was run in white-beam mode with no Fermi chopper. The PDF patterns of Ni and Al2O3 were refined using the PDFfit method and the results compared to data c...
