  • Patent number: 11651924
    Abstract: Methods of producing microrods for electron emitters and associated microrods and electron emitters. In one example, a method of producing a microrod for an electron emitter comprises providing a bulk crystal ingot, removing a first plate from the bulk crystal ingot, reducing a thickness of the first plate to produce a second plate, and milling the second plate to produce one or more microrods. In another example, a microrod for an electron emitter comprises a microrod tip region that comprises a nanoneedle that in turn comprises a nanorod and a nanoprotrusion tip. The microrod and the nanoneedle are integrally formed from a bulk crystal ingot by sequentially: (i) removing the microrod from the bulk crystal ingot; (ii) coarse processing the microrod tip region to produce the nanorod; and (iii) fine processing the nanorod to produce the nanoprotrusion tip.

  • Patent number: 11622439
    Abstract: An array of non-thermal plasma emitters is controlled to emit plasma based on application of an electric current at desired frequencies and a controlled power level. A power supply for an array controller includes a transformer that operates at the resonant frequency of the combined capacitance of the array and the cable connecting the array to the power supply. The power into the array is monitored by the controller and can be adjusted by the user.
