Abstract

We have developed a novel configuration concept of crystal chips for time-of-flight (TOF) crystal-analyzer neutron inelastic scattering spectrometers, which simultaneously achieve time-focusing, spatial-focusing and momentum-correcting abilities. This concept will be adopted for the planned TOF near-backscattering spectrometer, DIANA which has been proposed for construction at the Japan Proton Accelerator Research Complex (J-PARC). We will first discuss the new analyzer layout method satisfying both time- and spatial-focusing and momentum-correction concepts and then the focusing performances as evaluated by Monte-Carlo simulations and compared to the generally used energy-focusing analyzer configuration.
