Abstract

Details are given of a new proton microprobe recently commissioned at the Schonland Centre of the University of the Witwatersrand. The microprobe line is connected to two accelerators, a 6 MV EN tandem and a 2.5 MV Van de Graaff machine, for use in both more routine as well as research applications. Features of the target chamber allowing for rapid semi-automatic pump-down and the handling of multiple specimens are described, and details of the electronics and multi-parameter software are given. This software allows for the definition of multiple one- and two-dimensional gates, and runs under OS/2 on a 80386 based PC. Brief descriptions are given of some typical applications to illustrate the analytical potential of the system.
