嵌镶式无截获栅栅控电子枪的研究
AN INVESTIGATION ON THE NON-INTERCEPTING GRIDDED ELECTRON GUN WITH A SHADOW GRID EMBEDDED IN CATHODE
-
摘要: 本文给出了一种无截获栅糊控电子枪模型。阴影栅被直接嵌镶在阴极面上,阴影栅采用环形椰网,在计算机辅助设计中提出了简化二维数学模型并建立了计算程序。通过对计算机计算结果的分析,提出了设计这种枪的方法。并通过设计一个导流系数为0.9P的栅控枪进行了实验验证。初步结果表明建立的计算机程序完全可以满足这一类无截获栅栅控电子枪的工程设计要求。

Abstract: A kind of non-intercepting gridded gun is described, in which an annular grid-mesh type shadow grid is immediately embedded in the cathode. A simplified two-dimensional ma-thematical model is presented for computer aided design. Through investigation of the resu-Its of this computation a method of designing such a gun is presented. An experiment on a non-intercepting gridded gun with a perveance of 0.9 P is carried out. The obtained resu-Its prove that the computer program proposed here satisfies fully the design demand of this kind of non-intercepting gridded gun. -
