Multi-MeV Flash Radiography in Shock Physics Experiments: Specific Assemblages of Monolithic Scintillating Crystals for Use in CCD-Based Imagers

Figure 13

Resolution measurements of the imager for various scintillator thicknesses, using the regular roll bar method and an 18-MeV-bremsstrahlung spectrum, filtered with 10 cm of lead; the experimental images were analyzed to infer the line spread functions (LSFs) shown. Results for the 20-mm thick BGO assembly are shown on the left and results for the 30-mm thick BGO assembly are shown on the right: experimental results (thin black lines) and plots of the associated fit functions (thick gray lines).
