EXPERIMENTAL STUDY OF KINETIC SECONDARY ELECTRON EMISSION.

Abstract

The kinetic secondary electron emission of a single crystal of aluminum bombarded with Al(+) ions has been measured as a function of the orientation of the beam with respect to the crystal lattice, the energy of the ions, and the temperature of the target. The Al(+) ion beam is purified by magnetic filtering; its current density, of the order of 1 microA/sq mm, is high enough to maintain a clean target surface during the course of the bombardment. Teh results are interpreted in terms of the opacity of the crystal for the impinging ions. The influence of the overlapping of atoms and the validity of the hard sphere model is discussed. (Author)
