研究了半圆柱形二极管和被动阳极形成的高功率离子束的聚焦特性。研究了两种类型的聚焦二极管：外磁绝缘（单脉冲模式）和自磁绝缘的电子（双脉冲模式）。测量了离子束的能量密度分布和离子电流密度。有人发现，当二极管工作在双脉冲模式下，在焦平面中的最大离子束能量密度的区域相对于最大离子电流密度的区域被移位5-10 mm。它示出了具有最大能量密度的焦斑的移位的效果由离子束中大量加速的中性原子的存在来确定。这些原子是在离子二极管以双脉冲模式操作期间在离子二极管的阳极-阴极间隙中的离子电荷交换过程的结果。
The results of investigating the focusing of a high-power ion beam, which is formed by a diode with a semicylindrical geometry and a passive anode, are presented. Two types of focusing diodes were investigated: with external magnetic insulation (one-pulse mode) and self-magnetic insulation of electrons (twopulse mode). Measurements of the energy-density distribution of the ion beam and the ion-current density were performed. It was found that when the diode operates in the two-pulse mode, the region of the maximum ion-beam energy density in the focal plane is displaced relative to the region of the maximum ion-current density by 5–10 mm. It is shown that the effect of a displacement of the focal spot with the maximum energy density is determined by the presence of a large number of accelerated neutral atoms in the ion beam. These atoms are produced as a result of the ion charge-exchange process in the anode–cathode gap of the ion diode during its operation in the two-pulse mode.
