强电磁脉冲中电子的瞬时加速

Temporary Acceleration of Electrons While Inside an Intense Electromagnetic Pulse

Kirk T. McDonald, Konstantine Shmakov

摘要:

如果一个自由电子被一个强电磁波所超越,它可以暂时获得相当大的能量。原则上,如果在强激光束的存在下发生电子-电子、电子-正电子和电子-光子相互作用,该过程将允许大幅度增强这些相互作用的质心能量。实际的考虑严重限制了这个概念在当代激光入射到相对论电子上的实用性。一个更容易获得的实验室现象是通过强激光束入射到气体上产生电子-正电子。天体物理学起源的强电磁脉冲可以通过暂时加速的电子的韧致辐射导致非常高能的光子。

英文摘要:

A free electron can temporarily gain a very significant amount of energy if it is overrun by an intense electromagnetic wave. In principle, this process would permit large enhancements in the center-of-mass energy of electron-electron, electron-positron and electron-photon interactions if these take place in the presence of an intense laser beam. Practical considerations severely limit the utility of this concept for contemporary lasers incident on relativistic electrons. A more accessible laboratory phenomenon is electron-positron production via an intense laser beam incident on a gas. Intense electromagnetic pulses of astrophysical origin can lead to very energetic photons via bremsstrahlung of temporarily accelerated electrons.
