The software "Focus" modelling axi-symmetric electron-optical systems: algorithms and characteristics
In work the technique of numerical modelling electron- and ion-optical systems is advanced, algorithms and methods of high accuracy maintenance of function evaluation of potential distribution are offered by a boundary elements method, the technique of search of conditions of angular and spatial high orders focussing is developed. On a database of these methods the software for the path analysis of corpuscular optics systems is created, research of calculations errors and detailed testing on model tasks is carried out.
