Abstract
A cathode shield can comprise a shield body, a pair of tabs for defining a focal spot length, and a lip for concentrically aligning the cathode shield relative to a mounting element and/or an electron source of a cathode assembly. The tabs may be integral with the shield body and spaced a distance apart from each other. The distance may at least partially define the focal spot length of the electron source associated with the cathode assembly. The lip may also be integral with the shield body and extend from the shield body around at least a portion of a perimeter of the shield body so as to define a recess that is configured to receive the mounting element of the cathode assembly.
