Abstract

The approach for the modeling of corpuscular-optical systems for the analysis of charged particle flows is considered. For all the methods considered and used earlier, the condition of spatial focusing of the particle beam was required. However, this strict condition is not always feasible in combination with other requirements. When a cylindrical electrostatic mirror analyzer is used as the main element, spatial focusing of the beam is incompatible with focusing in time of flight in terms of energy. In the paper the possibility of using the collimation regime of charged particle beam is considered, thereby eliminating the need to fulfill the focusing condition.
