Abstract
Monte-Carlo simulations of a focusing supermirror guide after the monochrom ator on the IN14 cold neutron three-axis spectrometer, I.L.L, were carried out using the instrument simulation programs RESTRAX and McSTAS. The simula tions were compared to experiment to check their accuracy. Comparisons of t he flux ratios over both a 100 and a 1600 mm(2) area at the sample position compare well, and there is a very close agreement between simulation and e xperiment for the energy spread of the incident beam.
