摘要

为了提高自注入束的稳定性，研究人员考虑了改变在金属密度等离子体中激发唤醒场的两个激光脉冲序列的参数：抑制横向束衰减和增加等离子体中自注入束的存在时间。研究考虑了两种参数变化情况。在第一种情况下，考虑了两个激光脉冲参数的同时变化；在第二种情况下，考虑了其中一个激光脉冲变化后的参数集与另一个激光脉冲的参数集不同（2 个激光脉冲的剖面序列）。

IMPROVING STABILITY OF THE SELF-INJECTED BUNCH BY VARIATION OF A SEQUENCE OF TWO LASER PULSES PARAMETERS AT WAKEFIELD EXCITATION IN A METAL DENSITY PLASMA

The variation of parameters of a sequence of two laser pulses exciting wakefield in a metal density plasma are considered as a way to improve the self-injected bunch stability: suppression of transverse bunch decay and increasing the existing time of a self-injected bunch in plasma are investigated. Two scenarios of parameter variation were considered. In the first scenario, the simultaneous variation of the parameters of both laser pulses was considered; in the second scenario, the set of parameters for one of the laser pulses after variation differed from the set of parameters for the other laser pulse (profiled sequence of 2 laser pulses) was considered.
