Various instruments have been developed previously for analyzing the spectrum of energies of beams of charged particles emanating form surfaces and described in numerous publications [1]. Among all those instruments the concentric hemispherical analyser (CHA) and the cylindrical mirror analysers (CMA) have been the most often used instruments both commercially and for various devices developed by different laboratories. At first sight, geometry of the two analyser types is very different. However, topologically their geometries are very similar. This paper presents a line of thought where geometries of both analysers are just particular examples of a more general geometry that in turn provides numerous analyser configurations, that we now call spheroid energy analysers (SEA), often having excellent electron optical characteristics [2]. The SEA instrumental concept enables electron optical exploration of various new analyser embodiments, particularly well suited for chemical analysis of surfaces and surface nano-features. Progress in this instrumentation development and example spectra will be presented. References [1] D. Roy and D. Tremblay, Design of electron spectrometers, Rep. Prog.
