Energy analyser or energy analyzer may refer to: * A type of diagnostic probe used in the study of plasma physics * An electron energy analyzer, as used in

Auger Electron Spectroscopy A Hanford scientist uses an Auger electron spectrometer to determine the elemental composition of surfaces. Auger electron spectroscopy (AES; pronounced in French) is a common analytical technique used specifically in the study of surfaces and, ...

Electrostatic analyzer An electrostatic analyzer or ESA is an instrument used in ion optics that employs an electric field to allow the passage of only those ions or electrons that have a given specific energy. It usually also focuses these particles (concentrates them) ...
