利用永久磁场抑制中子管中的电子电流

Suppressing Secondrary Electron in Neutron Tube by Means of a Permanent Magnet

由于中子管中次级电子的存在,中子产额明显降低。主要讨论中子管中抑制次级电子的方法。

Secondary electron can affect the production of neutron very much. The paper major discuss the reason of the secondary electron be produced by and the means of disable the secondary electron .
