载流等离子体柱(Z-Pinch)的高方位磁场可用于收集和聚焦加速器中的高能带电粒子。描述了这种线性透镜的束流光学特性和与传统聚焦装置(如磁铁和磁喇叭)相比的明显优势。当等离子体透镜在常规的加速器运行中运行时，必须在很大程度上理解等离子体动力学的物理，并且必须掌握该技术。报道了用等离子体透镜收集反质子的等离子体动力学测量和长期行为测试的结果。鉴于反质子收集的预期性能，讨论了等离子体动力学控制和等离子体与壁相互作用的问题。
The high azimuthal magnetic field of a current-carrying plasma column (z-pinch) can be used to collect and focus high-energy charged particles in accelerators. The beam optics and the apparent advantages of such a linear lens compared with conventional focusing devices, such as magnets and magnetic horns, are described. When a plasma lens shall be operated in routine accelerator runs, the physics of the plasma dynamics must be largely understood and the technology has to be mastered. The results of plasma dynamics measurements and of long-term behavior tests with a plasma lens for antiproton collection are reported. The problems of the plasma dynamics control and of the plasma-wall interaction are discussed in view of the envisaged performance for antiproton collection.
