A LINEAR SHAPED CHARGE NEUTRON RADIOGRAPHY PRECISE DETECTION SCHEME
Neutron radiography was researched to detect the linear density of explosive in linear shaped charge (LSC), to determine its distribution uniformity and defective. The clear images of some samples were obtained by neutron radiography, and were processed to obtain the linear density of inner explosive. The defectives such as sparseness, discontinuity and cavity were shown clearly in the images. The method, with more intuitive and more reliable results, is more direct and simpler than existing quality testing methods for LSC, and most important, the method is a non-destructive one. This new method is of significance to the precise test of LSC and its application in precise blasting; in addition, it could be used in quality test of cord type explosive device.
The industrial uses of neutrons
Abstract This review describes some of the neutron scattering and radiography techniques that have been used to solve industrial problems. Over the last 10 yr the application of neutron scattering to industrial problems has grown as the techniques have evolved to study ever more complex systems. The four techniques that are most frequently used are diffraction, small angle neutron scattering (SANS), reflectometry and radiography. This review will describe the scope of these methods and illustrate some of the new problems that are now being solved suing accelerator-based sources.
