Schematic drawing of the experimental set-up. The polychromatic beam issued from the bending-magnet device (B) was reduced to a beam size to match the scintillator after passing through the slit (S). The X-rays irradiated the object (O) that was positioned 25 m away from the source. Visual images on the surface of the CdWO4 scintillator (St) placed at a distance of 5 cm from the object were reflected at 90° by a gold-coated mirror (M) and were magnified by a microscope objective lens (×10) (L). Finally, the images reached the CCD camera (Megaplus II ES 2001). |
