Popis: The energy straggling of heavy ion beams at tandem energies, passing through thin foils, has been studied with ions of mass up to A = 35. Charge exchange in the foils has been found to have a considerable effect on the energy spread. Thickness non-uniformities in the foils can also make significant contributions. Extrapolation of the observations to the case of a uniform carbon stripper foil in a tandem accelerator suggests energy straggling of the order a few tenths per cent of the beam energy. However, large non-uniformities in the foil could appreciably worsen the beam resolution.
