Abstract
The design, construction and operation of a low-energy, high-resolution electron impact spectrometer are described. Emphasis is given to the means by which a practical hemispherical deflector can be made to approach its hypothetical optimum performance. Attention is also given to the design of the accompanying electron transport systems and to empirical methods of achieving good energy resolution in order to exploit the capabilities of the electrostatic energy selector. The authors have obtained elastic scattering spectra containing features whose measured full widths at half maxima are 12 meV, and these are presented.Keywords
