ActiveNon-destructive testing—Thermal neutron radiographic testing—Determination of beam L/D ratio
无损检测 热中子照相检测 中子束L/D比的测定
Application Summary AI generated
This standard specifies the method for determining the L/D ratio (length-to-diameter ratio) of a thermal neutron beam used in neutron radiographic testing. It is applied in non-destructive testing contexts where thermal neutron imaging is used to inspect materials, such as detecting hydrogenous substances or internal defects in aerospace components, nuclear fuel assemblies, or explosive devices. The L/D ratio measurement ensures image sharpness and geometric resolution for accurate flaw detection and characterization.
