The collective acceleration of laser plasma ions in a magnetic field generated by a powerful fast-growing current pulse in a low-inductive conical spiral is studied. The velocity of ions for a number of elements which significantly differ in atomic weight are obtained on the basis of collector measurements. The maximum velocity of both light (lithium) and heavy (lead) ions exceed the value of 10⁸ cm/s; for ions of lead, the corresponding energy amounts to a value of ∼1 MeV. A mathematical model of ion acceleration is proposed and simulation results are compared with the experiment.

锥形螺旋脉冲磁场中离子的集体加速

研究了低电感锥形螺旋中由强大的快速增长的电流脉冲产生的磁场中激光等离子体离子的集体加速。基于收集器的测量，获得了原子量明显不同的许多元素的离子速度。轻（锂）和重（铅）离子的最大速度均超过10 ⁸ cm / s的值；对于铅离子，相应的能量约为1 MeV。提出了离子加速的数学模型，并将仿真结果与实验进行了比较。
