The paper dealt with two problems arised from the practics of dense electron gun design: Experimental measurements were made systematically for the equivalent an ode radius of practical electron guns. Method of calculations for electron beam comtours including the effect of space charge was derived from the field free of space charge. Results: It is proved that in the range of 1. 0-2. 5 microperveance the equivalent anode radius of practical electron guns meet good wth Muller's emperial...

The paper dealt with two problems arised from the practics of dense electron gun design: Experimental measurements were made systematically for the equivalent an ode radius of practical electron guns. Method of calculations for electron beam comtours including the effect of space charge was derived from the field free of space charge. Results: It is proved that in the range of 1. 0-2. 5 microperveance the equivalent anode radius of practical electron guns meet good wth Muller's emperial formula. The new method of calculation for electron beam contours is better than the old one (Brewer's).
