Energy Analysis
The unique Qtac100 energy analyser design is based on the advanced Calipso technology. At the optimum scattering angle, the analyser has an acceptance over the full azimuth. This, together with parallel energy detection, provides 3000 times higher sensitivity than conventional ion scattering spectrometers, thus enabling the non-destructive, reproducible and quantitative analysis of the top atomic layer. The high energy resolution of the Qtac100 allows the unambiguous identification of the analysed elements.
