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