Abstract

An original method has been developed to measure the lateral straggling ofsub-micron proton and alpha beams after passing through polymer foils of different thickness. For this purpose, the microbeam. line at CENBG has beenused in scanning transmission ion microscopy (STIM) configuration to deliver the ions in normal incidence on foils. The lateral spreading of the beamwas measured using a collimated charged particle detector centred on the beam axis and placed 6.3 min behind the foil. When the beam was horizontallyscanned in front of the collimator, its lateral distribution was measured step by step detecting particles passing trough the small aperture. Regulargaussian shapes were obtained and data were compared to the result of simulations carried out using the SRIM Monte-Carlo code for 2.5 MeV protons andalphas in Mylar and Formvar thin Mms.
