Abstract
We have produced thermionic cathodes using (100) oriented lanthanum and cerium hexaboride as the emission sources. These cathodes use the Vogel mount system for mechanical alignment and heating. While this mount is superior for mechanical stability we show methods to improve emission stability which are mount related.
