摘要：

The characteristics of an analyser consisting of two 180-degrees hemispherical deflection analysers placed in tandem and equipped with a multichannel detector have been investigated. The energy resolution and transit time spread for non relativistic electrons have been computed using numerical methods. The optimum size and shape of the entrance slit with respect to multichannel detection are considered. Electron energy spectra have been simulated for a multidetector with up to 100 discrete channels to show the ''snap-shot'' capability of the analyser.
