THE FEASIBILITY OF QUICK WARM-UP AND STABILIZATION OF HEATER-CATHODE TYPE RECEIVING TUBES

Abstract

The feasibility was studied of obtaining quick warm-up and stabilization of a triode heatercathode type receiving tube. The design and development is described of a simple stacked triode type tube employing a ceramic sandwich heater-cathode structure. The advantages offered by the metallized ceramic cathode in good thermal contact with the heater include: (1) the thin ceramic slab serves both as heater-cathode electrical insulation and as the rigid mechanical support for the planar metallizing, thus minimizing thermal storage, (2) operation time is favored by reduction of the thermal capacity of the heater-cathode, and (3) operation time is further reduced by increasing the rate of energy input throughout the heating of the cathode, as a result of conductive transfer.
