- Description
- Vis and Near-IR spectra of a pellet of "Saponite Griffithite", with different irradiation fluences.
- Number of spectra
- 4
- Variable type(s)

- irradiation dose
- Comments
- We irradiated a pellet of Saponite on the SIDONIE isotope separator at IJCLab (Orsay, France) using $He^+$ ions at 40 keV. The sample was mounted vertically and ion irradiation was performed at normal incidence. We measured four separate spectra corresponding to different fluences: $1.10^{16}$, $3.10^{16}$ and $6.10^{16}$ $ions.cm^{-2}$.
