ABSTRACT:
A radiation treatment apparatus comprises a source of charged particles, preferably protons, for producing a particle beam, and a scattering foil for changing the diameter of the charged particle beam. The scattering foil is configured so that its thickness is both uniform and continuously adjustable throughout a range of thicknesses.
