Abstract: An apparatus for an electron gun includes a one piece thermionic electron source that extends in a longitudinal direction and has opposite end portions, an aperture disposed therebetween, and two longitudinal portions that extend in the longitudinal direction and are spaced apart from one another by the aperture and rigidly joined together by the opposite end portions. The thermionic electron source is less susceptible to ion bombardment and therefore has a longer operating life than previous ribbon type electron sources. Further, because the electron source is one piece, it does not require support and relative positioning of multiple emitters such as that required by an electron source having two separate and parallel emitters.

Abstract: A method includes providing an electron gun having a first head with a thermionic electron source and an accelerating electrode, and further includes replacing the first head with a second head having a power rating substantially different than that of the first head, and subsequently operating the electron gun without replacing the accelerating electrode. The electron gun may further include a platform spaced apart from the accelerating electrode and having an adjustably located locating member that engages a reference member on the head to position the head in three dimensions relative to the accelerating electrode. The platform may be adjustably spaced from the accelerating electrode in order vary the distance between the electron source and the accelerating electrode.
