▼a Vacuum electronic devices (VEDs) serve an important role as high-power and/or high-frequency sources of RF radiation. To access higher power and higher frequency regimes, VEDs will require greater current densities and lower emittance electron b |

▼a In this dissertation, I motivate the need for a better understanding of these cathodes for application in VEDs. I show why emittance is such an important figure of merit for electron beams and how it relates to the beam current density. I demons |
