Images of scintillator output when exposed to an intense X-ray beam. LuAG scintillator, 100 µm thickness, 12 mm diameter, located 36 m from the X-ray source. Illumination from unfiltered APS bending-magnet white beam (beam size 3.15 mm × 3.15 mm). Images were recorded after the start of illumination of (a) 0.1 s, (b) 1.0 s, (c) 1.5 s, (d) 2.0 s and (e) 3.0 s. |
