| Zusammenfassung | The optical properties of thermionic triode electron guns, governed largely by the wehnelt, are studied in depth with the aid of a simple model. A unified theory of the beam energy characteristics-total current, brightness and energy distribution-emerges from these calculations. The use of emittance diagrams is explained and the role of the Boersch effect is explored. |
