摘要

采用磁偏转的方法，对金属氢化物电极真空弧离子源放电产生的等离子体进行了成分诊断。采用了TiD

电极材料进行放电，测量了在30-80 A弧流情况下的各离子的组分。实验结果表明，弧流越大时等离子体的密度越大，在现有引出结构下，由于等离子体发射面的凹凸变化导致测得的离子信号出现双峰。通过增加栅网可以减少等离子密度，双峰情况会有所减少。另外，随着弧流增大，氘所占比例会有所增加，弧流达到60 A以上氘含量增幅不明显。

Abstract

Background:

The metallic hydrogen(deuterium)electrode vacuum arc ion source which can discharge plasma mainly containing metal ions

hydrogen ions and deuterium ions

is generally used to the ion gun or the small accelerator.

Purpose:

To study the deuterium ions ratio affected by the arc current

the deuterium ion ratio produced by the discharge of vacuum arc ion source with metallic deuterium electrode was measured.

Methods:

To separate metal ions

hydrogen ions and deuterium ions

the magnetic analysis was used.And the ions current was measured by the scintillators and Faraday cups.

Results:

Experimental results showed that

within a certain range of arc current

the greater the plasma density is

the change of plasma emission surface affected the collective of ions current more obviously.And within the range of 30-80 A

deuterium ion ratio increased with the arc current

but the ratio became stable when arc current exceeded 60 A.

Conclusion:

The magnetic analysis platform can be used to obtain the deuterium ions ration of vacuum arc ion source.Within a certain range of arc current

the arc current can increase the deuterium ions ratio.
