In recent years, X-ray cargo inspection systems have been rapidly being installedat ports, airports, and borders to strengthen the security of baggage and the prohibition oftransaction with drugs and contraband. We at Korea Atomic Energy Research Institute arecurrently developing a dual-energy X-ray cargo inspection system. In this study, a 64-channelcharge sensitive readout system consisting of two 32-channel readout systems has been designedfor collecting and amplifying signal charges from detector arrays. The 32-channel readout systemwas composed of 8 detector arrays (four photodiodes per one detector array, 2 mm pitch), 32 holdswitches, 32 charge integrators, 32 reset switches, 32 sample-and-holds, 32 output switches, anoutput buffer, a frequency divider (divide by 4), and a 32-bit shift register. Each component waswell designed and optimized for our system, and the size of the fabricated circuit board is 135mm×71.5 mm. From the visible light tests, the output pulses and the corresponding images weresuccessfully acquired according to the intensity of the incident light.
