逆契仑柯夫聚焦激光电子加速器

本文提出逆契仑柯夫聚焦激光加速电子的基本原理。由粒子动力学分析表明,在满足契仑柯夫辐射条件下,可以对电子进行持续稳定的加速,而无需外加粒子聚焦系统。由于聚焦轴上激光电场就是加速电场,因此,它比已提出的逆契仑柯夫激光加速方案具有更高的加速场强。文中还指出这类加速机理的局限性。 关键词：

AN INVERSE CHERENKOV FOCUSING LASER ACCELERATOR

The principle of the inverse cherenkov focusing laser accelerator is presented. It is readily shown, by studying the dynamics of the charged particles, that the particles are accelerated steadily and continuously when the condition of the cherenkov radiation is satisfied, and need no additional focusing systems since the laser field on the focusing axis is just the accelerating field, so that the intensity of the latter may be higher than that in the previously proposed inverse cherenkov laser accelerator. The limitations of this accelerating mechanism are also discussed.
