Abstract :
At the Laboratori Nazionali del Sud (LNS), Catania, Italy, in the framework of digital radiography and ion beam diagnostics, the use of thin monocrystal scintillating plates made from CsI(Tl) has allowed us to obtain promising results in terms of high sensitivity, compactness, and handiness. In both techniques, a charge-coupled device camera is used to observe the light produced in the crystal when it is crossed by X-rays, in case of radiography, or by charged particles, in case of beam imaging. Spatial resolution has been measured with X-rays as a function of the plate thickness (100 μm to 2 mm), and particular care has been taken in order to perform the imaging of low-intensity radioactive beams (Ibeam<105 pps) that will be produced with the EXCYT facility at LNS
