Energy loss measurements of low energy ions in thin carbon foils

Abstract The energy losses in thin carbon foils of ions of N, Ne, Ar, Mn, Kr and Xe have been measured at 100 keV and 200 keV using a high-resolution magnetic spectrometer, with a view to improving the accuracy of beam-foil lifetime measurements. For high- Z particles, the results show that a straightforward application of the Linhard-Scharff-Schiott total stopping cross-sections to beam-velocity correction can substantially overestimate the reduction in velocity due to the foil.
