摘要
During the low-voltage aging of a completely-assembled and operative cathode-ray tube, a varying positive voltage is applied to the focus electrode and a constant positive voltage is applied to the screen electrode while the cathode is emitting electrons. The effect is to cause electrons from the cathode to scan or spray across the electrode surfaces causing outgassing by electron bombardment of the scanned surfaces. This results in higher and more stable cathode-emission levels.
