摘要

本文研究了短真空间隙下重复低电流放电的软x射线发射。在电弧消光后形成的阴极护套中的电场对电子进行加速，在电弧消光和随后击穿之间的一段时间内发射软x射线。纹影照片和Langmuir探针诊断结果表明，弧相形成了直径小于1 mm的微等离子体，离子鞘层以104/m/s的速度扩展，与计算结果一致。致密等离子体的存在时间为10 ~ 20ns。

Temporal evolution of micro-plasma in a repetitive vacuum arc soft x-ray source

Soft x-ray emission from a short vacuum gap, operated with a repetitive low-current discharge was investigated. Electrons are accelerated by an electric field in a cathode sheath that is formed after arc extinction, and soft x-rays were emitted in the period between arc extinction and subsequent breakdown. The schlieren photographs and Langmuir probe diagnostics showed that the micro plasma of diameter less than 1 mm is formed during arc phase, and the ion sheath extended with velocity of 104/m/s , which agreed with calculation. The existence time of the dense plasma was 10 - 20 ns.
