Abstract

We demonstrate that charged particles in a sufficiently intense standing wave are compressed toward, and oscillate synchronously at, the antinodes of the electric field. We call this unusual behavior anomalous radiative trapping (ART). We show using dipole pulses, which offer a path to increased laser intensity, that ART opens up new possibilities for the generation of radiation and particle beams, both of which are high energy, directed, and collimated. ART also provides a mechanism for particle control in high-intensity quantum-electrodynamics experiments.

摘要

我们证明，在足够强的驻波中的带电粒子会被压缩到电场的波腹处，并在波腹处同步振荡。我们将这种异常行为称为反常辐射俘获（ART）。我们使用偶极脉冲（这为提高激光强度提供了一条途径）表明，反常辐射俘获为产生高能、定向且准直的辐射和粒子束开辟了新的可能性。反常辐射俘获还为高强度量子电动力学实验中的粒子控制提供了一种机制。
