Abstract: An electron source includes a first electrode, a second electrode, a thermionic element interposed between and electrically isolated from the first electrode and the second electrode, and a guard electrode interposed between and electrically isolated from the first electrode and the second electrode. The thermionic element and the guard electrode may be at substantially the same voltage. Another electron source includes a first electrode, a second electrode, a thermionic element interposed between and electrically isolated from the first electrode and the second electrode, and a thermal expansion component interposed between and electrically isolated from the first electrode and the second electrode. The thermal expansion component may be heated to cause expansion. The heating may be cycled to cause alternating expansion and contraction.

Abstract: In a method and apparatus for adjusting a composite electric field to be applied to an ion trap to accommodate switching the operation of the ion trap between a positive ion mode and a negative ion mode, the composite electric field includes a plurality of component fields including at least one AC trapping field and one or more supplemental AC fields. A phase of one or more of the component fields is adjusted such that a force imparted by the composite field to a negative ion in the ion trap will be substantially the same as the force imparted by the composite field to a positive ion in the ion trap.
