The IS 40E1 Ion Source is a two lens, extractor type, focused, differentially pumped ion gun. The source is able to raster a 10 mm x 10 mm area of the surface at the recommended working distance. It is particularly suitable for depth profiling in XPS, ISS and SIMS. The source can be also used for sample surface cleaning.
