Proton-scattering radiography

Small-angle multiple scattering of high energy protons has recently been shown to give rise to an edge pattern which can be used for radiography. The authors derive the intensity pattern involved and discuss its implications for radiography. They also derive the degradation of the intensity pattern by obscuring matter and various instrumental effects and use it in design of arrangements for taking scattering radiographs with protons of 160 MeV and 7 100 MeV. Sample radiographs illustrate the main differences from, and advantages of the technique over, x-radiography recorded on film. The resemblance to xero-radiography is pointed out.
