摘要
本文通过广义协变的坐标变换导出了激光电子加速器中能量增益的表达式,指出即使不存在外加的引力场,电子也会因背景介质的影响产生一个附加的引力加速,在真空情况,所得结果与用洛仑兹变换得到的结果一致。
In this paper, we derive an expression of energy gain in a laser electron accelerator by using a general covariant coordinate transformation. It is pointed out that even when the external gravitational field, is absent, the electrons will still be additionally accelerated by the influence of background medium. In the vacunm case, the obtained results agree with those obtained by the Lorentz transformation.
