Abstract:
1. A system for providing a thermally optimized cold cathode heater, said system comprising: a heater wire disposed in a plurality of turns, wherein turns of said plurality of turns are closely spaced to concentrate heat in an area of a host cathode device corresponding to a cold cathode position, and wherein turns of said plurality of turns are disposed to minimize introduction of heat in an area of said host cathode device not corresponding to said cold cathode position; wherein said closely spaced turns of said plurality of turns comprise a first set of more than one turn corresponding to a first cathode of said host cathode device and a second set of more than one turn corresponding to a second cathode of said host cathode device; and wherein a low resistance conductor couples said first set of more than one turn to said second set of more than one turn.
