这里提出的结果表明，保罗陷阱模拟器实验（PTSX）利用两个系统中粒子横向动力学之间的相似性，模拟了强带电粒子束通过磁交变梯度（AG）传输系统在数公里的距离上的传播。对应于归一化强度参数 s=omega(2)(p)(0)/2omega(2)(q)<or=0.8 的等离子体已被捕获，其中 omega(p)(r) 是等离子体频率，omega(q) 是平滑聚焦近似中的平均横向聚焦频率。测得的光束均方根半径与模型一致，同样适用于 PTSX 和 AG 系统。 PTSX 装置将单组分铯离子等离子体限制数百毫秒，相当于光束传播超过 10 公里。
The results presented here demonstrate that the Paul trap simulator experiment (PTSX) simulates the propagation of intense charged particle beams over distances of many kilometers through magnetic alternating-gradient (AG) transport systems by making use of the similarity between the transverse dynamics of particles in the two systems. Plasmas have been trapped that correspond to normalized intensity parameters s=omega(2)(p)(0)/2omega(2)(q)<or=0.8, where omega(p)(r) is the plasma frequency and omega(q) is the average transverse focusing frequency in the smooth-focusing approximation. The measured rms radius of the beam is consistent with a model, equally applicable to both PTSX and AG systems. The PTSX device confines one-component cesium ion plasmas for hundreds of milliseconds, which is equivalent to over 10 km of beam propagation.
