Device for controlling operation of lithicon cathode-ray memory tube
Abstract
Cathode-ray memory tubes, lithicons, were developed which record television frames on the target surface with adequate quality for broadcasting without spontaneous erasure of the potentiall profile after turn-off or during lengthy storage. A device for controlling the operation of a lithicon was subsequently developed which ensures application of the proper voltages to three tube components (modulator, signal plate, erasing electrode) during three stages of the operating cycle (preparation for recording, recording, readout with normal erasure) and storage. The device consists, accordingly, of three arrays of four voltage generators each and one array of control-pulse generators. Better control of analog devices such as memory tubes will ensure their competitiveness against digital devices.
