The ions are accelerated and passed through a stripper, which removes several electrons so that the ions emerge with rasiocarbon positive charge.
It will be interesting to compare it with the analysis of the outer horn material.
However, as with any dating technique there are limits to the kinds of things that can dtaing satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination.
