Abstract
The new positive ion microprobe at the Schonland Centre is described a nd details are given of its configuration, its imaging system and soft ware. In a unique configuration, the microprobe has access to two acce lerators, a 6 MV EN tandem and a 2.5 MV single-ended machine. The imag ing system uses a CAMAC based system and runs on a personal computer u nder OS/2. The implementation of PIXE and treatment of thick-target da ta are presented. Applications discussed are analysis of tin artifacts from the prehistory of metallurgy in South Africa; a diamond-containi ng rock; carbonado, gold contained in pyrite and cogenetic minerals in cluded in diamond.
