Ion source IS 40E1
Ion Source IS 40E1 – two lens, focused, extractor type ion gun. Suitable for depth profiling (Ar), enables operation with reactive gases like O2, H2, hydrocarbons and all noble gases. 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.
