Abstract

Flows of ions with energies on the order of megaelectronvolts, which propagate both in the axial direction and in the direction perpendicular to the symmetry axis of the discharge, are recorded in a high-current low inductance vacuum spark. Estimates based on the measurements of the total charge of suprathermal electrons emitted from the region of the waist of the current channel in the axial direction, as well as the total number of ions of the indicated energies show that the recorded ion energies correspond quite well to the value that can be achieved as a result of the Coulomb explosion of the Debye waist layer at the stage preceding the radiation compression.

德拜层的库仑爆炸是在微夹层放电等离子体中形成高能离子流的一种机制

摘要

在大电流低电感真空火花中记录着能量在轴向和垂直于放电对称轴的方向上传播的兆伏级离子流。根据从电流通道腰部区域沿轴向发射的超热电子总电荷的测量值以及指示能量的离子总数进行的估算表明，记录的离子能量与在辐射压缩之前的阶段，由于Debye腰层的库仑爆炸而可以达到的值。
