Abstract: DYANA is an inverted-geometry time-of-flight (TOF) spectrometer proposed for the Japan Proton Accelerator Research Complex (J-PARC) project. Here, we show that by introducing pulse-shaping disk choppers and Si 111 analyzer, a DYANA-type short-incident-flight-path spectrometer can attain a very high energy resolution of 2 µeV, with an acceptable neutron flux at the sample position.
