  • Apparatus and procedure to characterize the surface quality of conductors by measuring the rate of cathode emission as a function of surface electric field strength
    Patent number: 8863568
    Abstract: A device and method for characterizing quality of a conducting surface. The device including a gaseous ionizing chamber having centrally located inside the chamber a conducting sample to be tested to which a negative potential is applied, a plurality of anode or “sense” wires spaced regularly about the central test wire, a plurality of “field wires” at a negative potential are spaced regularly around the sense, and a plurality of “guard wires” at a positive potential are spaced regularly around the field wires in the chamber. The method utilizing the device to measure emission currents from the conductor.
