Investigation of symmetrical two-cylinder lens.

Ali A. Al-Azawy


In the current work, The immersion lens was investigated as a two-cylinder symmetrical lens with different radii, and this lens is studied in the accelerated mode and in the deceleration mode. Their main points have been studied in these cases. Where firstly the lens has a negligible gap width and secondly with a dysfunctional gap width, and all the cardinal points can be obtained as a function of the voltage ratio.
