ABSTRACT:
An electronic storage tube of the electron beam modulated type employing a target structure of the "coplanar grid" type in which the coplanar grid is a multilayered structure having at least one layer thereof which is more immune to ionizing radiation, such as X-rays, than at least one of the remaining layers, to yield a target structure in which erasure time and retention time are both significantly improved even though the stored pattern is repetitively read out.
A method is also described herein for operating target structures of the type described hereinabove to take advantage of the above mentioned advantageous characteristics and thereby yield an electronic storage tube having operating characteristics not heretofore capable of being provided in conventional structures.
