Quantitative autoradiographic measurement of the scattering of protons in a krypton gas target
A study on the measurements of proton current density profiles determined by the scattering process in natural krypton gas resulted in the development of a quantitative autoradiographic technique for the determination of a proton induced activity distribution on a Cu foil. Application of this technique showed that a 24 MeV, 1 μA proton beam with a FWHM of 7.3 mm was enlarged to a beam with a FWHM of about 43.5 mm for a target length of 50 cm and a Kr gas pressure of 400 kPa. For a comparison the target was also filled with Xe gas resulting in a larger FWHM value than for krypton under the same experimental conditions.
