ABSTRACT:
During low-voltage aging of a completely assembled cathode-ray tube, at least three voltage spikes at least three minutes apart are applied to the heater. Each spike has a voltage peak higher than the constant voltage applied to the heater during low voltage aging, and lasts for up to 120 seconds. This results in higher average emission levels and a reduced tendency of the emission levels to slump during emission testing of cathodes so processed.
