Charge-state distributions of 20 Ne ions emerging from thin foils

Abstract

New experimental measurements of charge state distributions produced by a 20 Ne 10+ beam at 15 MeV/u colliding on various thin solid targets are presented. The use of the MAGNEX magnetic spectrometer enabled measurements of the 8 + charge state down to fractions of a few 10 −5 . The use of different post-stripper foils located downstream of the main target is explored, showing that low Z materials are particularly effective to shift the charge state distributions towards fully stripped conditions. The dependence on the foil thickness is also studied and discussed. © 2019 The Author
