Abstract
The invention relates to storage tubes having a dielectric target in which the writing is effected by a beam of slow electrons supplying the target with negative charges in an amount which is a function of the data to be written. The new method mainly consists in: causing each writing of a zone of the target to be followed by a sweeping of said zone with rapid electrons supplying at each written point a small quantity of positive restoring charges, whereby it is possible to reach an equilibrium potential within a finite and regulatable time while avoiding the phenomenon of integration.
