摘要

在唤醒场激发的井喷状态下，唤醒场会发生强烈的混沌化。然而，对于电子-正电子对撞机和 X 射线显微镜，提出了一种弱非线性机制，即形成规则的短气泡链。为了提高唤醒场加速器的效率，有必要让不独立的气泡串参与其中。本文在二维平面几何中研究了形成气泡的数量及其正则化对唤醒非线性程度和参数的依赖性：驱动电流、离子迁移率、横向等离子体尺寸和剖面 。我们将证明，在弱非线性状态下，规则气泡链会变得更长。

REGULARIZATION OF WAKEFIELD IN A WEAKLY NONLINEAR REGIME

In blowout regime of wakefield excitation, strong chaotization of wake occurs. However, for electron-positron colliders and X-ray microscopes, a weakly nonlinear regime is proposed with the formation of a regular short chain of bubbles. To increase the efficiency of the wakefield accelerator, it is necessary that not separate bunches participate. In this paper in 2D plane geometry, the dependence of the number of formed bubbles and their regularization on the degree of wake non-linearity and parameters: driver current, ion mobility, transverse plasma size and profile is studied. We will show that in a weakly nonlinear regime the regular chain of bubbles becomes longer.
