Abstract

Transportation and focusing of intense heavy-ion beams is an important issue for heavy ion beam-driven inertial confinement fusion and physics of high energy densities. Application of plasma lens offers certain advantages over traditional systems based on quadruple lenses. A description of the plasma lens with high-power high-current (up to 400 kA) TDI-pseudosparks as switching elements and experimental results of preliminary studies of plasma lens designed for heavy ion accelerator-accumulated facility TWAC-ITEP are reported. It is shown that a focusing capability of plasma lens depends on a stage of plasma discharge development. In a particular stage it is possible to employ sharp focusing and compress the beam into a very small spot. In other stages when the magnet field is non-linear it is possible to shape various beam configurations, in particular, tube structures. In the report the results of investigations implemented with beams of C+6 and F+6 ions with energy of 200 MeV/a.e.m. are reported. The obtained results are analyzed.

等离子体透镜转化tdi -伪火花ITEP重离子加速器

强重离子束的传输和聚焦是重离子束驱动惯性约束核聚变和高能量密度物理研究的重要问题。等离子体透镜的应用比传统的基于四倍透镜的系统具有一定的优势。报道了以大功率大电流(高达400 kA) tdi伪火花作为开关元件的等离子体透镜的描述，以及为重离子加速器积累装置TWAC-ITEP设计的等离子体透镜初步研究的实验结果。结果表明，等离子体透镜的聚焦能力取决于等离子体放电的发展阶段。在一个特定的阶段，可以采用锐利聚焦并将光束压缩成一个非常小的点。在其他阶段，当磁场是非线性的，可以塑造各种光束的配置，特别是管结构。用能量为200mev /a.e.m的C+6和F+6离子束进行了实验研究。报告。对所得结果进行了分析。
