WebPast Auger spectrometers used several types of electron energy analyzers, including spherical sector and cylindrical mirror analyzers. However, modern instruments nearly always incorporate cylindrical mirror analyzers because their high transmission efficiency leads to better signal-to-noise ratios. WebAug 31, 1995 · The electron-optical properties of a cylindrical-mirror analyser with a non-uniform edge field have been numerically investigated. It is shown that the performance of an instrument with a non-ideal cylindrical field can considerably exceed that of an idealized instrument. Cylindrical mirror analyser Electron energy analyser
