Abstract
By introducing a channel in the moderator of a coal analysis setup using neutron-induced gamma technique, more fast neutrons can reach the coal. Then the characteristic gamma-rays of C and O are increased due to neutron inelastic scattering (NIS) reaction, and measurement of the two elements is sufficiently improved. Monte-Carlo simulations have been carried out in this work for the setup with different prism channels. These prism channels have different positions and sizes, but their bottom surfaces are all nearby the neutron source. The results show that, it could obtain the optimum improvement of C and O measurement, by selecting a proper position and size for the prism channel.
