Claim of US Patent No. 9,659,741

1. An electron emitter comprising:
a plurality of elongate rungs connected together end to end from a first emitter end to a second emitter end in a plane so
as to form a planar pattern;

a plurality of corners, wherein each elongate rung is connected to another elongate rung through a corner of the plurality
of corners, each corner having a corner apex and an opposite corner nadir between the connected elongate rungs of the plurality
of elongate rungs;

a first gap between adjacent non-connected elongate rungs of the plurality of elongate rungs, wherein the first gap extends
from the first emitter end to a middle rung;

a second gap between adjacent non-connected elongate rungs of the plurality of elongate rungs, wherein the second gap extends
from the second emitter end to the middle rung, wherein the first gap does not intersect the second gap; and

one or more cutouts at one or more of the corners of the plurality of corners between the corner apex and corner nadir or
at the corner nadir.
