Abstract: The deconvolution of inelastic neutron scattering data requires the knowledge of the inelastic resolution function. The inelastic resolution function of the time-of-flight spectrometer IN5/ILL has been measured by exploiting the sharp resonances of the roton and maxon excitations in superfluid [sup 4]He for the two respective (q, ω) values. The calculated inelastic resolution function for three different instrumental setups is compared to the experimentally determined resolution function. The agreement between simulation and experimental data is excellent, allowing us in principle to extrapolate the simulations and thus to determine the resolution function in the whole accessible dynamic range of IN5 or any other time-of-flight spectrometer. or Lorentzian functions [6]. A more convenient way, which gives much insight into how R[sub in,el] (q, ω) is affected by the instrument layout, is to perform Monte Carlo (MC) simulations. Furthermore, for the design of the disk-chopper TOF spectrometer TOF-TOF [7] that is going to be built at the FRM-II we used extensive and detailed MC simulations [8]. Therefore, our aim was to measure R[sub in](q, ω) of a disk-chopper TOF spectrometer, in our case IN5/ILL, directly. Thus it is possible to calibrate and test the validity of our simulations at an existing TOF spectrometer. [ABSTRACT FROM AUTHOR]
