摘要

研究了激光驱动尾流场加速的气泡状态下有限发射度电子束对电子束本身微观结构的影响。使用弹性反向传播(Rprop)来寻找平衡结构,我们观察到对于实际和已经观察到的发射,先前发现的晶体结构保持完整,只是略微加宽。较高的发射率导致晶体内较大的电子位移,最终导致晶体破裂。

Finite-emittance Wigner crystals in the bubble regime
We study the influence of finite emittance electron bunches in the bubble regime of laser-driven wakefield acceleration onto the microscopic structure of the bunch itself. Using resilient backpropagation (Rprop) to find the equilibrium structure, we observe that for realistic and already observed emittances the previously found crystalline structures remain intact and are only widened marginally. Higher emittances lead to larger electron displacements within the crystal and finally its breaking.
