论文摘要
可用的分析韦克场模型，用于气泡的模型和电子血浆加速度的爆发状态完美地描述了重要特征，例如形状，田野，捕获比，可实现的能量，能量分布和径向发射。正如我们所显示的，对于具有极小幅度的韦克菲尔德，这些模型无法描述加速电场及其在韦克菲尔德后方的差异。由于诸如光学电极注入的特洛伊木马状态之类的突出参数策略具有此功能，因此，制定解决此问题的分析模型非常重要。这项工作引入了一种可能的模型。使用现象学理论，我们能够更好地描述电场和气泡形状的差异。
Available analytical wakefield models for the bubble and the blow-out regime of electron-plasma acceleration perfectly describe important features like shape, fields, trapping ratio, achievable energy, energy distribution and radial emittance. As we show, for wakefields with an extremely small amplitude these models fail to describe the accelerating electric field and its divergence in the wakefield rear. Since prominent parameter regimes like the Trojan horse regime of photocathode injection exhibit this feature, it is of great importance to work out analytical models that fix this problem; one possible model is introduced in this work. Using a phenomenological theory, we are able to better describe the divergence of the electric field and the bubble shape.
