经典电动力学中带电粒子任意运动的能量损失
Energy loss by the arbitrary moving charged particle in classical electrodynamics
摘要:
计算了任意运动带电粒子产生的电磁场通过大半径球体时的能量脉冲流。将所得公式应用于双曲运动粒子产生的辐射问题和同步辐射能量损失问题。运动带电粒子辐射的能量脉冲不是一个不变的4-张量,因此,基于参考系变化的计算方法是不正确的。
英文摘要:
The energy-impulse flow of electromagnetic field, produced by the arbitrary moving charged particle, through the sphere of large radius is calculated. The result formulae are used in problem of radiation produced by hyperbolically moving particle and the problem of the synchrotron radiation energy loss. The energy-impulse radiated by a moving charged particle is shown to be not an invariant 4-tensor, for this reason calculation methods based on change of reference frame are not correct.
