Indirect Geometry TOF Spectrometer with Crystal Analyzer on Pulsed Neutron Source

Abstract

We briefly introduce the principle of measurement for inelastic and quasielastic scattering and the specification of DNA. The time-of-flight (TOF) type near-backscattering spectrometer (n-BSS), DNA, with Si crystal analyzers was built and operation was started in 2012 at the Materials and Life Science Experimental Facility (MLF) of the Japan Proton Accelerator Research Complex (J-PARC). DNA is the first n-BSS equipped with a pulse shaping chopper installed at spallation pulsed neutron sources.
