Cathode ray tube storage target having increase life

A cathode ray storage tube, comprising:

• an evacuated envelope;
• a storage target mounted within said envelope including a conductive coating in contact with one side of an insulative support member and a storage dielectric layer in contact with said conductive coating, said storage dielectric layer containing a mixture of storage dielectric material and rare earth material selected from the group consisting of a rare earth oxide, a rare earth oxysulfide and a rare earth activated rare earth oxide or oxysulfide;
• writing means mounted within said envelope for bombarding said storage target with a writing beam of high velocity electrons and for deflecting said writing beam across said storage target to produce an electron image in accordance with input information on said storage dielectric layer corresponding to said input information;
• and
• holding means mounted within said envelope for bombarding said storage target substantially uniformly with low velocity electrons in order to cause said electron image to be stored bistably for an indefinite controllable time on said storage dielectric layer.
