Popis: An electron energy spectrometer of straight and two-stage retarding field type is presented, where the electric potential on the axis is chosen symmetric as Ф(z) ∝ exp (α|z|/L) for −L≤ z≤L (α: positive eigenvalue) in each stage. According to the solution of the trajectory, the spectrometer is so designed as to filter electrons with double focusing. The energy resolution of a compact spectrometer is 2–3 eV in the range of 50–2000 eV and that of a longer one is less than 1 eV. The spectrometers have worked satisfactorily in measuring Auger electrons emitted from ion-atom and electron-atom collisions.
