论文摘要
在这项工作中，我们研究了由于存在两个发生高斯振幅波动的两种反向传播的FEL束碰撞而导致的田地，从真空中研究了电子峰值对的产生。我们的工作旨在通过包括固有的随机幅度波动的固有随机振幅波动来扩展以前的作品。如图所示，根据过程的顺序，可以预期在多光子体制中的一个大强度窗口上，可以预期创建对数量的大型非线性增强。还讨论了关于未来关于在FEL设施中产生超强和高能辐射的计划的真空对创建。
In this work we study the production of electron-positron pairs from vacuum in presence of a field resulting from the collision of two counter-propagating FEL beams that undergo Gaussian amplitude fluctuations. Our work aims to the extension of previous works based on the standing wave hypothesis, by including the inherent stochastic amplitude fluctuations of the individual FEL beams. As shown, depending on the order of the process, a large non-linear enhancement in the number of created pairs can be expected over a big intensity window in the multi-photon regime. Vacuum pair creation in view of future plans on the production of ultra-strong and high energy radiation in FEL facilities is also discussed.
