Abstract
The combination of a storage tube and a feedback circuit operatively intercoupled such that as data is read from the storage tube the level of stored charge on each incremental area of the dielectric of the tube's target is sensed and the potential between the cathode and target conductor is automatically adjusted as a function of the sensed charge level. This feedback control of the aforementioned potential allows for the use of a larger differential charging range on the target's dielectric, which in turn provides a substantial improvement in the fidelity of data processing through the storage tube.
