AN ANALYZING SYSTEM FOR CONCURRENT ENERGY AND ANGULAR-DISTRIBUTION MEASUREMENTS OF CHARGED-PARTICLES EMISSION

A theoretical treatment of an electron-optical scheme is suggested. Th e system can be used for simultaneous registration of energy and angul ar distributions of charged particles (electrons or ions) emitted from a small source. The scheme is based on an axially calculated symmetri cal electrostatic field. The source has the form of a short interval o f the axis of symmetry. The system consists of a novel type of electro static energy analyser and an usual planar position-sensitive detector joined to it.
