Query: A comparison of Monte-Carlo simulations using RESTRAX and McSTAS with
  experiment on IN14   Monte-Carlo simulations of a focusing supermirror guide after the
monochromator on the IN14 cold neutron three-axis spectrometer, I.L.L. were
carried out using the instrument simulation programs RESTRAX and McSTAS. The
simulations were compared to experiment to check their accuracy. Comparisons of
the flux ratios over both a 100 mm2 and a 1600 mm2 area at the sample position
compare well, and there is very close agreement between simulation and
experiment for the energy spread of the incident beam.
