Activity
High pressure mineral physics and experiments at large scale facilities
Diamond anvil cells
Research team: Earth and Planetary Materials.
Contacts: Sébastien MERKEL, Julien CHANTEL.
The diamond anvil cell allows the experimental study of mantle materials and the Earth's core. The sample is compressed between two diamonds having a flat surface with a diameter ranging from 10 to 700 μm. The properties of the sample are then studied by diffraction or spectroscopy. The laboratory has several cells, allowing in-situ experimentation at pressures above the megabar. For temperatures below 1500 K, the sample can be heated using a graphite furnace fitted inside the diamond cell. Samples can also be heated to temperatures of several thousand degrees by focusing on the sample of power lasers (10 to 100W, infra-red). This operation allows the activation of phase transitions with slow kinetics, to relax the constraints within the samples, and to reproduce the conditions of the interior of the planets. The laboratory does not have a laser heating system and we occasionally use assemblies installed in other laboratories or during our in-situ campaigns on large instruments.
Electro-erosion drill
Research team: Earth and Planetary Materials.
Contacts: Sébastien MERKEL, Julien CHANTEL.
Fast, accurate and centered drilling of metal joints used for diamond cell experiments.
Fluorescence and Raman spectroscopy
Research team: Earth and Planetary Materials.
Contacts: Sébastien MERKEL, Julien CHANTEL.
The fluorescence spectrum of the ruby is particularly useful for measuring the pressure applied in a diamond cell. Indeed, the rubies doped with Cr3 + ions emit a spectrum whose lines are shifted with the pressure. Raman spectroscopy probes vibrations in crystals, liquids and glasses. The changes in the spectra induced by the pressure can be interpreted in terms of changes in the arrangement of atoms and the motions of these atoms.
Micro digital milling machine
Research team: Earth and Planetary Materials.
Contacts: Julien CHANTEL, Nadège HILAIRET.
This tool allows the production of prototypes or small series of metal or ceramic parts for so-called 'big volume' experiments (piston-cylinder and multi-anvils).
Micro-drill
Research team: Earth and Planetary Materials.
Contacts: Sébastien MERKEL, Julien CHANTEL.
Column precision drill, used for part making for so-called 'big volume' experiments (piston-cylinder and multi-anvils).
Micromanipulator
Research team: Earth and Planetary Materials.
Contacts: Sébastien MERKEL, Julien CHANTEL.
Allows handling of items smaller than 10µm when preparing diamond cell experiments.
Microwave welder under neutral atmosphere
Research team: Earth and Planetary Materials.
Contacts: Julien CHANTEL, Nadège HILAIRET.
Fine welding technique by instant fastening for all metals. Used to hermetically seal the metal capsules of so-called 'big volume' experiments (piston-cylinder and multi-anvils).
Piston-cylinder press
Research team: Earth and Planetary Materials.
Contacts: Nadège HILAIRET, Julien CHANTEL.
This press, with a solid confinement medium, allows experiments at pressures up to 4 GPa and temperatures of 1800 ° C, on samples pluri-millimeter to centimetric. This device contributes to the synthesis of innovative materials, the production of materials with controlled compositions and microstructures, the synthesis of synthetic rocks and the sintering of natural or synthetic rocks.

Wire saw
Research team: Earth and Planetary Materials.
Contacts: Nadège HILAIRET, Julien CHANTEL.
