提出了一种研究带电粒子束晕形成的可能的实验方法。它是基于一个紧凑的单组分等离子体陷阱装置使用射频四极或螺线管磁场的粒子约束。原则上，该系统可以再现高强度光束传输通道中的实际情况，从而使人们能够对空间电荷主导的光束和晕特性进行系统的实验研究。我们描述了一个示例设置的系统，它是可能的，以探索晕的程度上的失配因子的依赖关系，以及对调抑郁症，多极扰动的影响，横向纵向耦合效应在聚束束与各种纵横比，发射度增长由于粒子内碰撞等。
A possible experimental approach is proposed to investigate halo formation in charged particle beams. It is based on a compact one-component plasma trap devise using either a radio-frequency quadrupole or a solenoidal magnetic field for particle confinement. In principle, the system can reproduce actual situations in high-intensity beam transport channels and, thus, enables one to perform systematic experimental study of space-charge-dominated beams and halo properties. We describe an example setup of the system where it is possible to explore the dependence of halo extent on mismatch factor as well as on tune depression, the effect of multipole perturbations, transverse–longitudinal coupling effects in bunched beams with various aspect ratios, emittance growth due to intra-particle collisions, etc.
