提出了一种将等离子体电子注入等离子体尾流场加速阶段的新方案。在该方案中，单个短电子脉冲穿过低密度等离子体，并具有急剧的、局部的、向下的密度转变。在该转变附近，由于该区域中感应尾波的波长快速增加，许多背景等离子体电子被捕获在等离子体尾流场中。使用二维细胞内粒子模拟验证了该方案的可行性。为了进一步研究捕获和加速机制，进行了 ID 哈密顿量分析以及一维模拟，并对结果进行了展示和比较。
A new scheme fur plasma electron injection into an acceleration phase of a plasma wake field is presented. In this scheme, a single, short electron pulse travels through an underdense plasma with a sharp, localized, downward density transition. Near this transition, a number of background plasma electrons are trapped in the plasma wake field, due to the rapid wavelength increase of the induced wake wave in this region. The viability of this scheme is verified using two-dimensional particle-in-cell simulations. To investigate the trapping and acceleration mechanisms further, a ID Hamiltonian analysis, as well as 1D simulations, has been performed, with the results presented and compared.
