摘要
Abstract
In mass production for the pulse grid-controlled TWT,the unstable phenomena of emission current is observed. The problem is analyzed and studied from two sides* First,we focus on the consistency of the emission capability from cathode itself, Second , we notice that the distances between cathode and control grid are different in some products and do lots of research on the architecture of electron gun, especially to constable the distance between cathods and gid in it* The results show that the yield of cathode emission is improved by 30% by a building sampling test method of cathodes* The lower temperature of electron gun and the higher pulse voltage are avoided by controlling appropriately the distances between cathode and control grid. The above methods guarantee the stability of cathode*s emission current-关键词
