  • Cylindrical mirror electrostatic energy analyzer free of third-order angular aberrations
    Patent number: 4367406
    Abstract: A cylindrical mirror electron spectrometer includes an additional electrode between the usual inner and outer cylinders. The additional electrode is maintained at a potential slightly more negative than the equipotential present without the electrode. The spectrometer can be dimensioned and the relative electric potentials on the three electrodes can be chosen so as to provide for third order focusing of electrons diverging from an axial source.
