Abstract

The post-deflection acceleration lens with spherical mesh grid in oscilloscope tubes are calculated with the aid of a digital computer. The paraxial behaviour of the post-deflection acceleration lens of different geometries

such as the position of the focal point

the focal length and the scan magnification

are given by numerical calculations. Several experimental tubes have been measured and the theoretical analyses are given. The results are useful for design of CRT.
