Abstract
The results of two different approaches in simulation of image converter tube electron optics are given. The first approach is based on aberrations technique, and the second one is connected with trajectories analysis. To compare the efficiency of both techniques we have chosen an electron-optical system of the very well- known time analysing image-converter tube of PVOO1 type. Our digital results reveal much higher calculation stability for the aberration technique when the latter was used for calculation of the image tube parameters near the tube axis. For the photocathode points shifted of the tube axis, both approaches exhibit the similar behaviour. Furthermore, for the photocathode peripheral areas the software based on trajectories analysis seems to be more preferable. It is evident that further development of both techniques will provide the same accuracy and calculation stability over the whole photocathode area for various type of electron lenses.
