It has been found that high-intensity beams can be monitored using calcium fluoride and PEN films of different thicknesses for light ions. The intensity range is 10^-3~10^1 nA/cm^2 for 10-MeV protons. As a result, a large-area uniform ion beam can be adjusted efficiently at a high intensity of the order of 10 nA/cm^2, which is often required for radiation degradation/damage testing of materials.}, title = {Investigation of Phosphor Screens for Real-time Tuning of Large-area Ion Beam Profile}, year = {2017} }
