Back bombardment for dispenser and lanthanum hexaboride cathodes

Back bombardment for dispenser and lanthanum hexaboride cathodes

The back bombardment (BB) effect limits wide usage of thermionic rf guns. The BB effect induces not only ramping-up of a cathode’s temperature and beam current, but also degradation of cavity voltage and beam energy during a macropulse. This paper presents a comparison of the BB effect for the case...
