Patent ID: 10269529

Abstract:
A method of designing an electron emitter can include: determining a desired cross-sectional profile of an electron emission from an electron emitter and inputting parameters of the electron emitter into a computer; determining a desired temperature profile for the electron emitter that emits the desired cross-sectional profile; and determining desired emitter dimensions for a defined electrical current through the electron emitter that produces the desired temperature profile with the computer based on the input parameters of the electron emitter. The emitter dimensions can include: each rung width dimension; each first gap segment dimension; each second gap segment dimension; and each web dimension. The emitter can include: a plurality of elongate rungs connected together in a planar pattern; a plurality of corners; a first gap between adjacent non-connected elongate rungs; a second gap between adjacent non-connected elongate rungs; and one or more cutouts between a corner apex and corner nadir.
