Electron model experiments of a perfect focusing mass spectrometer were carried out with respect to the perfect velocity focusing and to the perfect directional focusing. The validity of these perfect focusing properties was verified by the use of electrons in energy from 10<SUP>3</SUP>eV down to 10eV or less. A luminousity of more than98%was attained in the lower energy range and90% in the higher energy range for both cases of s=1and s=2, where s is a field parameter connecting electric field with magnetic field. A resolution of this spectrometer was also measured as a function of various experimental parameters such as an acceleration energy of electrons, field parameter s, a detector width or a position of the detector. These experimental results were compared with the results of calculations by an electronic computer. They showed good agreement within the experimental errors.
