Title: Optimised design of a ROTAX-type instrument

Abstract

The rotating analyser (ROTAX) spectrometer has been devised and installed at ISIS. Practical scans in (Q{h_bar}{omega}) space with a nearly arbitrary scan direction, i.e. polarisation of q vs. Q are possible and feasible with no compromises on the resolution. Valuable technological and methodological knowledge has been compiled for an improved version of such a type of instrument. At present ROTAX lacks competitiveness with other spectrometers from an unexpectedly weak neutron flux of its particular beam-line and an unfavourable adaption of the analyser`s drive power to the time frame or neutron source frequency.
