Abstract

This note describes a technique which uses colour film to provide semi-quantitative energy analysis as well as information on the spatial distribution of protons emerging from thin single-crystal foils. Characteristic “star patterns”, which are produced when a well-collimated proton beam is incident parallel to a major crystal direction, appear red on a yellow background, and show clearly the two distinct energy groups corresponding to the channelled and random components.
