摘要
§1.引言 从1974年以来,美国Sandia国家实验室的J.A.Holblieb等陆续发表了存在常磁场或真空区存在电磁场时电子输运问题的Monte-Carlo方法。但解法的叙述比较简略,也没见到解法等价性证明。1981年他们在Bull.AM.Phys.Soc。上报导曾经考虑过物质区存在常电场的情况,但没发表具体内容。
In this paper, the precise mathematical and physical foundations of the Monte-Carlo me-thod for electron transport with the electromagnetic field are established. The condensed histo-ries method given by M. J. Berger is generalized to the case where electromagnetic field existsin the material region. The full continuous-slowing-down method and the coupling methodof continuous-slowing-down and catastrophic collision are compared. Using the approxim-ation of homogeneous electronic field, the thickness of material for shielding the supra-ther-mial electrons produced by laser light irradiated target is evaluated.
