Isobaric molecules suppression by a surface stripper for the AMS system with ion energy below 50 keV; A Numerical study

Matsubara, Akihiro; Fujita, Natsuko ; Kimura, Kenji

We numerically estimated the suppression efficiency of the surface stripper in the case of the grazing incidence of the $^{13}$ CH with energy of tens of keV onto a single crystal surface in measurement of radiocarbon. The obtained survival probability of $^{13}$ CH falls to below 10 $^{-12}$ at which the level is required for the practical use. This suggests the sufficient dissociation capability of the surface stripper.
