We report on the secondary electron yields of Au and oxidized aluminum (Al2O3) by impact of heavy ions with energies ranging from 7.92 MeV/amu (12C6) to 2.54 MeV/amu (107Ag47). The obtained results, the first in this energy range using medium-heavy ions, extend the validity of proposed scaling laws obtained with lighter ions. Measurements have been performed using the SIRAD irradiation facility at the 15 MV Tandem of the INFN Laboratory of Legnaro (Italy), to evaluate the performance of ion electron emission microscopy at SIRAD.

Abstract

We report on the secondary electron yields of Au and oxidized aluminum (Al2O3) by impact of heavy ions with energies ranging from 7.92 MeV/amu (12C6) to 2.54 MeV/amu (107Ag47). The obtained results, the first in this energy range using medium-heavy ions, extend the validity of proposed scaling laws obtained with lighter ions. Measurements have been performed using the SIRAD irradiation facility at the 15 MV Tandem of the INFN Laboratory of Legnaro (Italy), to evaluate the performance of ion electron emission microscopy at SIRAD.
