Description
Visible and Near-IR spectra of phyllosilicate pellets at different irradiation fluences of $Ar^+$ (40 keV).
Number of spectra
12
Variable type(s)
  • sample composition
  • irradiation dose
Comments
We irradiated pellets of different terrestrial phyllosilicates on the SIDONIE isotope separator at IJCLab (Orsay, France) using $Ar^+$ ions at 40 keV. Samples were mounted vertically and ion irradiation was performed at normal incidence. For each sample, we measured, besides the "virgin" spectrum, three separate spectra corresponding to different fluences: $5.10^{15}$, $1.10^{16}$ and $2.10^{16}$ $ions.cm^{-2}$.
