Abstract
A cathode head can include: an insulating member on a base; an electron emitter with a planar emitter surface formed by a plurality of elongate rungs connected together through a plurality of turns from a first emitter end to a second emitter end so as to form a serpentine emitter pattern; a plurality of elongate legs extending from the plurality of turns at an angle relative to the planar emitter surface, each of the legs being coupled with the insulating member; an elongate first lead leg at the first emitter end and an elongate second lead leg at the second emitter end; a first electrical lead and a second electrical lead extending from the base; and a first electrical coupler coupling the first electrical lead to the first lead leg and a second electrical coupler coupling the second electrical lead to the second lead leg.
