Abstract :
The additional broadening of the time distribution of a pulse of neutrons associated with path length uncertainties caused by multiple reflections within a guide is generally small. This can become considerable for long wavelength instruments on a pulsed neutron source. This paper reports calculations for both the straight and the curved guide.
