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.
