This paper presents a new transport scheme and applies it to a simple modeling problem of an industrial CT. The results show that for an important class of problems, FC-NEE is much more efficient than geometry splitting with Russian roulette, DXTRAN or conventional analog transport methods.

文摘Pulse height cannot be easily tallied with commonly used analog transport methods when the recording cells are much smaller than the whole particle transport system. This paper presents a new transport scheme and applies it to a simple modeling problem of an industrial CT. The results show that for an important class of problems, FC-NEE is much more efficient than geometry splitting with Russian roulette, DXTRAN or conventional analog transport methods. The new method has been tested on an MCNP benchmark.
