Some Aspects of the Profoling of Electron Irradiation Fields by Scattering Foils

Popis výsledku v původním jazyce

With the use of formulae derived by Moliere and others the angular distributions of electrons scattered on Al foils have been calculated for electron energies E0 =10, 15, 20, 22 and 25 MeV. Theoretical results are compared with flux density measurementsof 22 MeV electrons, scattered by a 0.16 mm Al foil, with a Faraday cup at distances 100 to 150 cm from the beam exit window, and at distances 110 and 130 cm for electrons scattered by Al foils 0.16, 0.26, 0.36, 0.46 and 0.66 mm in thickness. A strongdependence on the beam aperture, due to the broad beam scattering effects in air, was observed. Semiempirical formulae for beam apertures 1.56 and 4.6 degrees were derived, which reproduce well the experimental results of forward peak electron flux dens ity(electrons.cm-2.s-1mA-1) for 1mA of total beam current as functions of the distance from the beam exit window and of the thickness of the Al scattering foils.
