Abstract

The paper describes a cathode-ray tube capable of storing an array of binary digits on a special target surface. The target surface incorporates a mesh which is sensibly coplanar with the storage surface and, therefore, simple to manufacture by evaporation. An attempt was made to develop a storage system that would combine the advantages of mesh storage with the simplicity of control of the Williams-Kilburn system in two steps, namely, transfer of control to the bright-up mechanism and the elimination of transient voltages on the mesh. The store for comparable spot size has a greater packing density than the normal non-mesh cathode-ray tube store, and at low speed operation the output signal is controllable both in amplitude and sign. The limits of the output signal amplitude are discussed and methods of improving the speed of operation and output amplitude are described.
