Abstract
New detector module based on screen type scintillators coupled photodiode has been proposed and estimated for the condition of dual X-ray baggage inspection. The new detector consisted of the Lanex Regular coupled photodiode for low energy detector and Lanex Fast-B coupled photodiode with copper filter of 1.1 mm thickness for high energy detector. By using simulation tools of MCNPX, DETECT 97, and ATLAS, optimum detector structure was designed and analyzed on Z-map. Compared with the commercialized detectors of Detection Technology (DT) and Electron Tube (ET), the proposed detector showed good performance property in the dual X-ray baggage inspection.
