BOND INSPECTION BY SCANNING IMAGES IN SCINTILLATING CRYSTALS,
Abstract
Characteristics of filmless methods of bond inspection for large diameter motors are presented. High energy radiation after traversing the bond area of a motor impinges on a sodium iodide crystal, which transforms the radiation intensity into a light pattern. This image on the crystal is scanned with an optical scanning system. A photomultiplier converts the light to an electrical signal, which is then displayed on an oscilliscope. Limitations of the system due to the relatively poor image formation ability of a scintillating crystal are given. Data are presented on detectable slit sizes using a 10 Mev betatron and 14 inches of low atomic number materials. (Author)
