Abstract :
A procedure for the design of a gridded converging beam electron gun is described. This procedure has been used to design several gridded guns in the perveance range of 
to 
. The characteristics of these gridded guns are compared with the design objectives. A method of calculating the grid control characteristics is developed. This-method utilizes charts compiled from measurements made in an electrolytic tank and the space charge potential distribution and yields both the grid drive and cutoff voltages. Grid control characteristics as determined by using these design charts are compared with those measured for experimental guns.
