Previous sample
Spherical particles of salty H2O ice (67 µm average diameter, 10 wt.% NaCl, Sample d). Before electron irradiation.
Sample made of spherical particles of salty H2O ice (SPIPA-B type, 67 µm average diameter) frozen from a 10 wt.% Nacl solution (Sample d). After first electron irradiation at 1 µA (1 keV). The VIS reflectance spectrum is collected over the outlined Region of Interest (red).
