中文摘要：

用粒子模拟研究了在激光尾波场电子弓形波注入过程中激光脉冲的横向波形对尾波场俘获电子数目的影响,发现与高斯激光相比,超高斯形激光更有利于拉动空泡闭合前侧边的电子团向空泡尾部汇聚形成高能量局域化的弓形波,从而导致更多的电子注入到空泡的加速相,使得被俘获的电子数目提高近5倍,且电子束品质得到改善.该研究对于进一步理解尾波场加速中电子注入等有参考价值.

英文摘要：

In this paper we study the effects of transverse profile of incident laser on trapping of electrons in an electron bow-wave injection regime. By using the particle-in-cell code, we find that the super-gaussian profile laser pulse can drive more energetic electrons of the electron bow-wave into the bubble with higher longitudinal injection velocity. At last, the total number of trapped electrons increases almost 5 times. And the quality of electron beam is also improved obviously.
