Abstract

A theoretical and experimental study of wakefield excitation by a profiled sequence of relativistic electron bunches in the plasma-dielectric structure, the parameters of which provide the conditions for the excitation of a small decelerating field for all driver bunches with simultaneous growth with the number of bunches of the accelerating total wakefield was carried out. Theoretically, the transformation ratio was found for the parameters of the experiment as the ratio of the total wakefield of the sequence to the field that decelerates driver bunches. In the performed experiments, the total wakefield was measured by the microwave probe. The magnitude of the decelerating field is determined by the shift of the maximum of the spectrum measured by the magnetic analyzer before and after wakefield excitation in the structure. The obtained transformation ratio increases with the number of bunches in the sequence and significantly exceeds this one for a nonprofiled sequence.

等离子体-介电韦克菲尔德加速器驱动电子束序列的细化

本文对等离子体-介电结构中相对论性电子束分布序列激发尾流场进行了理论和实验研究，其参数为所有驱动束激发小减速场提供了条件，并随加速总尾流场束数同时增长。理论上，实验参数的变换比为序列的总尾流场与驾驶员串减速场之比。在实验中，用微波探针测量了总尾流场。减速场的大小由磁分析仪在尾流场激励前后测得的波谱最大值在结构中的位移决定。所得到的转换比率随着序列中束的数量增加而增加，并且显著超过非剖面序列的转换比率。
