Abstract
FIELD: radio engineering. SUBSTANCE: device has cathode 1 which is shaped as pellet, holder 2, spiral heater 3, insulation 4, additional spiral heater 6 which is mounted above heater 3, additional spiral heater 6 decreases heat transmission from heater 3 to insulation 4, excludes contacts between heater 3 and insulation 4. The latter excludes fusion of insulation in points of contact. EFFECT: increased reliability and durability. 1 dwg
