摘要
Abstract
The internal quality of energetic material grains directly determines the safety and damage efficacy of weapon systems.Defects such as cracks and component segregation induced by molding processes are difficult to be effectively identified by conventional nondestructive testing(NDT)methods.X-Ray imaging is an ideal technique due to its strong penetration and density sensitivity,but existing scintillator materials suffer from poor stability or susceptibility to radiation degradation.Herein,rare earth ion-functionalized Eu/Tb@MOF-808 scintillators were prepared.The results show that the Tb@MOF-808 scintillator film achieves a resolution of 12.5 LP/mm,and Eu@MOF-808 reaches 7.1 LP/mm.The system can clearly identify penetrating cracks with a width of approximately 300 μm,metal particle distribution,and structural contours inside the grain.This technology provides a high-resolution,intrinsically safe solution for quality assessment and online screening of energetic grains.关键词
