1. A device comprising:

  • a cathode having a cathode surface;

    an anode having an anode surface that is exposed to a vacuum; and

    a dielectric body disposed between the anode and the cathode, the dielectric body having a dielectric surface that is exposed to the vacuum;

    wherein the dielectric surface and the anode surface approach each other such that an angle measured across the vacuum between the dielectric surface and the anode surface decreases with decreasing distance between the dielectric surface and the anode surface until the dielectric surface and the anode surface meet and are parallel.
