This EBCCD camera consists of a 24 mm photocathode, a high voltage intensifier tube (ranging from 5 to 10 kV) and a CCD chip with 1024×512 useful pixels. The size of the CCD pixels is 13.3×13.1 μm2. The sensitive area of the imaging zone is 13.4×6.7 mm2, whereas the useful area of the photocathode is 20.78×12.0 mm2 (demagnification factor is 0.56). A 12-bit ADC, on the border of the EBCCD electronics, provides the digital output. The sensitivity threshold is about 5×10-5 lux. This characteristic allows detection of low-light images as well as a reduction in exposure time and the irradiated dose.A diagram of the detection system configuration is shown in figure 5. A 30×40 cm2 GOS screen is mounted on the entrance window of a large box that both acts as a support and provides proper shielding for the detection system. By changing the distance between the EBCCD and the scintillating screen and adopting a suitable lens on the photocathode, it is possible to obtain highresolution images of a smaller area and a radiographic zoom of a specific zone. The set-up is similar to that of the micro-CT system, but this intensified system permits investigation of bigger objects with a resolution of about 200 μm (depending on the distance from the detector and screen and the magnification factor).
