Abstract : This report summarizes research work under an ordnance development contract for advanced development of television x-ray image enlargment systems and image storage media, for use in nondestructive testing inspection of metallic and nonmetallic missile case materials. The use of storage system with the television imaging system permitted integration of weak image signals to useable levels. An image was produced from x-radiation intensities as low as 4 milliroentgens. Television x-ray images were produced by a slow-scan camera chain with about 1/7 of the x-radiation intensity required by standard frame-rate system. Slow-scan video signals produced from x-ray images were successfully recorded on standard audio-frequency tape and reduced on a slow-scan television screen. A 2-inch-diameter x-ray-sensitive camera tube was fabricated and successfully tested. Its sensing area was approximately 7 times greater than 1-inch-diameter camera tubes. (Author-PL).
