Abstract
An electron spectrometer system is described with some illustrative spectra. The system combines the requirements of scanning Auger microscopy with those of high resolution spectroscopy. The spectrometer is a concentric hemispherical analyser with a four-element input lens and can be operated with a high signal sensitivity, low energy resolution (Ca 7eV window), with 0.1 sr angle or with a high resolution and reduced sensitivity.
