Abstract

The new positive ion microprobe at the Schonland Centre is described and details are given of its configuration, its imaging system and software. In a unique configuration, the microprobe has access to two accelerators, a 6 MV EN tandem and a 2.5 MV single-ended machine. The imaging system uses a CAMAC based system and runs on a personal computer under OS/2. The implementation of PIXE and treatment of thick-target data are presented. Applications discussed are analysis of tin artifacts from the prehistory of metallurgy in South Africa; a diamond-containing rock; carbonado, gold contained in pyrite and cogenetic minerals included in diamond.
