Abstract

Recent studies reported that PIG negative hydrogen ions extraction for neutron tube is superiority to positive hydrogen ions extraction. Present maturing products of neutron tube on market almost use PIG ion source and extract positive hydrogen ions. If negative hydrogen ions extraction can be applied on present products, the combination property will be greatly improved. In this study, a contrast experiment of PIG positive and negative hydrogen ion source for D–T neutron tube is put into effect. The relationships between the current of ion source, the beam current and the voltage extraction are investigated. The experiment results demonstrate that the negative ion extraction has higher yield of neutron for unit target current. We also point out that the ratio of yield to target current is a considerable parameter to reflect the overall performance of neutron tube.

中子管的猪正，负氢离子源对比实验

摘要

最近的研究报道，用于中子管的PIG负氢离子提取优于正氢离子提取。目前市场上中子管的成熟产品几乎都使用PIG离子源并提取正氢离子。如果可以在本产品上进行负氢离子萃取，则结合性能将大大提高。在这项研究中，进行了D–T中子管的PIG正负氢离子源对比实验。研究了离子源电流，束流和电压提取之间的关系。实验结果表明，负离子萃取对单位目标电流具有较高的中子收率。
