PROCESS OF ACTIVATION OF OXIDE CATHODE OF CATHODE-RAY DEVICES Russian patent published in 1995 - IPC

Abstract RU 2034353 C1

FIELD: electronic devices. SUBSTANCE: voltage is fed to modulator during activation with pulse duration 200-700 μs and repetition frequency 0.5-1.5 Hz. When current of individual cathode reaches specified value supply of pulse voltage to it is stopped and filament voltage is disconnected when values of currents at all cathodes reaches required value. EFFECT: improved reliability of process. 2 cl, 1 tbl
