Where does the maximum voltage come from in a vacuum capacitor?

The breakdown is a two step process. When the voltage becomes high enough you get field emission from the surface of the capacitor plates. With perfectly smooth surfaces this is all that happens, but with real surfaces you get points where the emission is enhanced due to surface irregularities.
