Using a carbon beam as a probe to extract the thickness of sensitive volumes

The upset rate calculation depends on the energy deposited along the secondaries paths in a sensitive volume (Sv) of thickness d. We have developed a new extraction method in order to get d from experimental data. It is based upon the deconvolution of the heavy ion upset cross section function /spl sigma//sub seu/(r) with LET(r) (r is the range of the incident ion).
