Performance and application of the scienta ESCA300 spectrometer

Abstract

Abstract The Scienta ESCA300 is a state‐of‐the‐art x‐ray photoelectron spectrometer with high intensity, and high energy and spatial resolution. This unique combination of features is made possible by the use of a high‐power rotating anode x‐ray source with monochromatization, high transmission and imaging electron optics and a multichannel detector. The first ESCA300 has been installed recently at ICI Wilton. We report on the performance of this instrument for conducting samples and as a microanalytical device. Also described are its performance for insulating samples (polymer films) and studies of charge compensation using the Bremsstrahlung‐induced electrons from an unmonochromated dual anode x‐ray source.
