A cathode head (15) can include: an insulating block (226) on a base (216); an electron emitter (222) with a planar emitter surface (234) formed by a plurality of elongate rungs (235) connected together through a plurality of turns (236) from a first emitter end (233 a) to a second emitter end (233b) so as to form a serpentine emitter pattern (230); a plurality of elongate legs (240) extending from the plurality of turns (236) at an angle relative to the planar emitter surface (234), each of the legs (240) being coupled with the insulating block (226); an elongate first lead leg (231a) at thefirst emitter end (233a) and an elongate second lead leg (231b) at the second emitter end (233b); a first electrical lead (227a) and a second electrical lead (227b) extending from the base (216); anda first electrical coupler (224a) coupling the first electrical lead (227a) to the first lead leg (231a) and a second electrical coupler (224b) coupling the second electrical lead (227b) to the secondlead leg (23lb). 种阴极头(15)可
