中子管靶面二次电子抑制

Principle and method of controlling second production of electrons from target surface

通过实验给中子发生器的靶的上方加一抑制电压 (负电压 ) ,使靶表面发射的二次电子受到抑制 ,从而使中子管达到更好的工作状态。

A demonstration of an experiment was carried out, in which prohibitive voltage is added to the upper target of the neutro generater to control the second production of electrons from the surface of the target in order to make the neutro tube work in a better condition.
