摘要
We have developed the only non-destructive technique to profile graded dopants in ICF shells to the precision required by the NIF specifications (Doping level must be accurate to 0.03 at. % and its radial distribution accurate to submicron precision). This quantitative contact radiography method was based on precision film digitization and a dopant simulation model. The measurements on Cu/Be and Ge/CH shells agree with those from electron microprobe and X-ray fluorescence.
