Abstract

See full text

The present invent provides a particle detector for counting and measuring the flight time of secondary electrons and scattered ions and neutrals and to correlate coincidences between these and backscattered ions/and neutrals while maintaining a continuous unpulsed microfocused primary ion beam for impinging a surface. Intensities of the primary particle scattering and secondary particle emissions are correlated with the position of impact of the focused beam onto a materials surface so that a spatially resolved surface elemental and electronic structural mapping is obtained by scanning the focused beam across the surface.
