Schematic representation of the origin of the Kossel lines. (a) The Kossel (1936[link]) method. (b) The divergent-beam method developed by Lonsdale (1947[link]). (c) The proton-induced Kossel effect (Geist & Ascheron, 1984[link]). In (b), the divergent X-ray beam is directed onto the sample from a point source while in the remaining cases it is generated within a crystal by (a) electrons or (c) protons.
