论文摘要
使用2D3V代码LCODE，通过形状的相对论电子束对非线性尾域激发的数值模拟具有电荷分布的数值，根据高斯电荷分布增加至最大值，然后急剧降低到零，然后执行。由于考虑到韦克菲尔德的非线性，已研究了变压器比，作为束内部最大加速场与束缚中最大减速场的比率，并加速了韦克菲尔德的比率。变压器比率和最大加速场对束长度的依赖性通过束的恒定电荷进行了研究。考虑到非线性韦克菲尔德的长度随着束长度的增加而增加。结果表明，对于束的一定长度，变压器比率达到其最大值。由于束的分析以及韦克菲尔德的非线性，变压器比率的最大值达到了6个。
Using 2d3v code LCODE, the numerical simulation of nonlinear wakefield excitation in plasma by shaped relativistic electron bunch with charge distribution, which increases according to Gaussian charge distribution up to the maximum value, and then decreases sharply to zero, has been performed. Transformer ratio, as the ratio of the maximum accelerating field to the maximum decelerating field inside the bunch, and accelerating the wakefield have been investigated taking into account nonlinearity of the wakefield. The dependence of the transformer ratio and the maximum accelerating field on the length of the bunch was investigated with a constant charge of the bunch. It was taken into account that the length of the nonlinear wakefield increases with increasing length of the bunch. It is shown that the transformer ratio reaches its maximum value for a certain length of the bunch. The maximum value of the transformer ratio reaches six as due to the profiling of the bunch, and due to the non-linearity of the wakefield.
