论文摘要
我们研究有限发射器电子束在激光驱动的韦克赛场加速度对束本身微观结构的气泡状态中的影响。使用弹性反向传播（RPROP）查找平衡结构，我们观察到，对于现实且已经观察到的发射率，先前发现的晶体结构保持完整，并且仅略微扩大。较高的发射量导致晶体内的电子位移较大，最终导致其破裂。
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.
