Abstract : Two types of scan-conversion storage tubes based upon the Permachon camera storage tube were developed, and both tubes utilize a fiber-optics photon transfer (FOPT) target for the signal conversion mechanism. The smaller of the two tubes, the WX 4640, is 16-1/2 in. long, 1-1/2 in. in diameter, and contains an FOPT target with a 3/4-in. diameter useful area. The reading gun in this tube is electromagnetically focused and deflected, while the writing gun is electrostatically focused and electromagnetically deflected. The large scan- converter, the WX 4821, is 31 in. long, 3 in. in diameter, and has an FOPT target with a 2-in. diameter useful area. Both of the electron guns in this tube are electrostatically focused and deflected. This report summarizes all the development work performed on the Permachon scan-converters, including recently obtained data on charge-down subsequent to erasure, aperture-response, and flood-beam holding. Also included as an Appendix are additional data on characteristics measured from the WL 7383 Permachon camera storage tube.
