ELECTRONIC STORAGE TUBE TARGET STRUCTURE AND METHOD OF OPERATION

摘要

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.
