Outlook

• Motivation• Space Payload Constraints• Chinese Wall Painting• Pigments on a Greek Vase• Were Celtic weapons burnt in sacrifices?• Miniature from the XV Century• Supporting Restoration of a Roman Mask• Archaeological artefacts are unique pieces• Non-destructive analysis is necessary• MIMOS II:

• Works on backscatering geometry

•Does not require sample preparation

•Is Portable

Constraints of MIMOS II

• Weight (~ 400 g)

• Vibrations

• Power (~ 3 W)

• Size (5x5x9) cm3

• Backscattering

• Calibrations

Conclusions

• MIMOS II is a suitable tool for archaeological applications.

• MIMOS II could provide non-destructive analysis of a variety of archaeological artefacts.

• Data from MIMOS II supported hypothesis of burning weapons after battles (magnetite to maghemite)

• Data from MIMOS II supported the restoration of a roman mask.
