Abstract
Long life high performance grid-controlled electron gun has been great extensive used in multi-beam klystron. High performance grid-controlled electron gun is the base of modern high power and broadband multi-beam klystron. We developed a tight and efficient electron gun; its perveance can be more than 0.5 micro-perveance of only one cathode.The whole electron gun has 28 independent small cathodes. The total of whole gun's perveance can be more than 18 micro-perveance. The characteristics of the gun are given in this article.
