Solid-state detector design for mobile cargo container inspection system using medium energy X-ray

Abstract

X-ray inspection system in these days has been used for the detection of illegal drugs, agricultural product and other contraband in custom application, and for the detection of weapons and explosives in security application. This paper presents how to design and realize mobile cargo container inspection system using medium energy, 450kVp X-ray, which is appropriate for Korean circumstance. Particularly, X-ray detector design is treated relatively in detail, since there are few papers on X-ray detector design for rapid and nonintrusive container inspection system. The spatial and contrast resolution of mobile cargo container inspection system developed in this paper are 2.0mm and 4%, respectively. The design method suggested in this paper may be applied to X-ray inspection system using higher energy.
