束团形状异质结中的空间电荷效应

Space Charge Effects in Bunch Shape Monitors

A. V. Feschenko, V. A. Moiseev

摘要:

利用相干变换将分析束流的时间结构变换为线靶发射的低能次级电子的空间结构的束团形状变换的操作和参数受所研究的束流特性的影响。聚束的电磁场干扰次级电子的轨迹,从而导致相位分辨率的降低和相位读取的误差。另一个效应是由于聚束引起的导线中的电流以及由于次级电子的电流补偿发射而引起的目标电势的扰动。给出了仿真的方法、模型和结果。

英文摘要:

The operation and parameters of Bunch Shape Monitors using coherent transformation of time structure of an analyzed beam into a spatial one of low energy secondary electrons emitted from a wire target is influenced by the characteristics of a beam under study. The electromagnetic field of a bunch disturbs the trajectories of secondary electrons, thus resulting in a degradation of phase resolution and in errors of phase reading. Another effect is the perturbation of the target potential due to the current in the wire induced by a bunch as well as due to current compensating emission of the secondary electrons. The methods, the models and the results of simulations are presented.
