Description
NIR spectra of Mighei meteorite pellet, before and after ion irradiation at different doses.
Variable(s)
irradiation dose
Number of spectra
5
Instrument
Bruker Tensor
Sample holder
The sample is mounted on a vertical holder in the vacuum chamber of INGMAR setup (IrradiatioN de Glaces et Météorites Analysées par Réflectance VIS-IR, IAS-CSNSM/Orsay)
Standard medium
vacuum
Spectral range type(s)
NIR
Valid spectral range(s)
Min - Max ($cm^{-1}$) Sampling ($cm^{-1}$) Resolution ($cm^{-1}$) Position accuracy ($cm^{-1}$) Absorption edge
#1 4011.40844562 - 11756.5316351 16.0 1.0
Incidence angle(s)
20.0°
Emergence angle(s)
15.0°
Phase angle(s)
15.0°
Observation mode
single spot
Spatial resolution
3000.0 ${\pm}$ 1000.0 ${\mu}m$
Comments
The collecting spot size is 3–4 mm, larger than the pellet heterogeneity, and thus representative of all constituents of the meteorite (matrix and chondrules).
