This report covers the evaluation of a number of advanced X ray converter screens. It concentrates in particular on screen types that are compatible with direct fiber optic readout. The new converters included several types of scintillating fiber optic screens, intagliated phosphor screens and depositions of high efficiency screens directly on fiber optic couplers. The study covered the X ray potentials between 20 KV and 320 KV. The report also describes the use of these screens with a solid-state line scan sensor and the advantages that such a sensor has in high resolution real-time radiography. Illustrations are provided on applications of this new technology to inspection of aerospace, electronic and ordnance samples. A design for an advanced solid-state line scanner is presented and its performance parameters predicted. Keywords Real time radiography, X ray converters, Screens.
