The intensity of ultra cold neutrons transmitted along a copper tube has been calculated by Monte Carlo techniques and compared with experimental intensities and with pure diffusion theory calculations. The possibility of focussing ultra cold neutrons by using a conical tube is also illustrated by this technique.
