While the idea to use charged particles for radiography is known since 1960’s, the technique was not widely used because scattering in the radiographed sample caused a substantial image blur. A way to overcome this blur was discovered in the 90’s at the Los Alamos National Laboratory by using a set of magnetic quadrupole lenses to image the object on the detector, and to correct chromatic aberrations.
Based on this experience, the proton microscope PRIOR (Proton Microscope for FAIR) is currently under construction at GSI. Its spatial resolution of less than 10 µm will by far exceed the capabilities of other proton radiography systems available at LANL (Los Alamos) and ITEP (Moscow).
Here we present a first design of the designated detector system for future dynamic experiments with PRIOR, which consists of a scintillator screen and a high resolution CCD camera. Geant4 Monte Carlo simulations have been carried out for optimizing the detector performance.
