摘要: In a cylindrical mirror analyzer, charged, particles from a source are deflected in the radial electric field between a pair of coaxial tubular electrodes, and are brought to a focus. A collector aperture positioned at the focus selects particles of predetermined energy, these particles being detected by a suitable detector. The particles cross the axis at some point between the source and the focus. An apertured member located at this point prevents skew electrons (i.e. electrons not travelling in radial planes) from reaching the focus. In this way the performance of the analyzer is improved.

摘要: An electron spectroscopy apparatus has an analyzer and a retardation lens system. In a first mode of operation, no retardation is applied, and the analyzer scans a low-energy range of the energy spectrum. In a second mode, retardation is applied, and the analyzer scans a high-energy range. The retardation is varied in synchronism with the scanning of the analyzer, so as to maintain a constant retardation factor.
