Abstract
A storage target having a collector electrode formed in a striped or latticed pattern on a storage substrate which is fabricated from a single crystal of electrically insulating material. Preferably, the storage substrate is of a single rhombohedral crystal of aluminum oxide or of a single isometric crystal of magnesium oxide, spinel, or calcium fluoride.
Claims1
A scan converter tube, comprising an evacuated envelope, electron beam generation means, electron beam deflection means and a storage target, said storage target comprising a storage substrate fabricated from a single crystal of aluminum oxide having a purity of more than 99.9% and a collector electrode on one face of said storage substrate, the collector electrode being in the form of a metal film having a plurality of regularly patterned openings formed therein with a pitch of about 10 to 50 microns, and the electrode density of the storage target being in the range of from about 0.1 to 0.4.
