- Name
- Sublimation mantle of Smectite on Water ice and Smectite intra-mixture particles 67±31 μm
- Database
- Experimentalists
- Date
- 2014-07-30
- Diameter
- 30.0 $mm$
- Sample changes
- After 28.31h of sublimation, a desiccated layer made of pure smectite, about 7.64±0.57 mm thick, covers the ice particles.
- Substrate material
- aluminum sample holder
- Substrate comments
- The sample is positionned in one of the four 60x30 mm compartments dividing the rectangular 120x60 mm sample holder with a thickness of 20mm
- Comments
- The initial thickness of the whole sample is 20 mm. During the experiment, the thickness of the layers in this sample is variable. See "Sample Changes".
- Temperature
- 211.0 $K$
- Type
- vacuum
- Fluid pressure
- 1.0e-05 $mbar$
- Comments
- The sample was kept under secondary vacuum
- Source
- Quartz window at 240 K
- Chronology
- before and during spectrum
- Irradiation time
- 28.31 $\pm$ 0.01 $h$
- Comments
- The quartz window has a temperature around 240 K during the operation at low temperature, resulting in an irradiance of about 50 W.m-2 onto the sample when placed at its standard vertical position, 7 cm below the window (Pommerol et al., 2015)
