HIGH-CURRENT-DENSITY CATHODE-RAY TUBE ELECTRON SOURCE.
Abstract
The life test of a large version of this cathode has passed 9300 hours and is still in progress. Emission being drawn, with the cathode operation at 1000 C and 115-118 volts d.c. being impressed on the anode, went through a minor peak of about 4.4 amperes per sq cm at 5600 hours, then it continued to fall off gradually to the present value of about 3.8 amperes per sq cm. This test demonstrated an inherent long-life capability of the cathode material which is being applied in the ultrahigh-resolution cathode-ray tube under investigation. (Author)
