Abstract
An approach to determining optimal sizes of collimators used for producing the initial phase set of a charged particle beam with the maximal volume at the inlet to the probe-forming system is described. This ensures beam focusing to a spot on a target with preset parameters and with the maximal current. The dynamics of phase sets is considered taking into account nonlinear effects associated with aberrations.
