Dimpler
Platform: Electron Microscopy Platform (PMEL).
Contact: Anne-Marie BLANCHENET.
he Dimpler is a precision instrument used for grinding circular dimples in the surface of materials. The Dimpler The sample is placed on a horizontal plane rotating around a vertical axis and a grinding wheel rotating
around a horizontal axis. The dimple technique produces with minimal damage a thin region
in the disk (thickness less than 50 μm) while leaving a relatively thick support border surrounding the thin
region and thus providing a very robust sample. A chemical or ionic thinning then makes it possible
to obtain large transparent areas.
Applications: Many materials can be dimpled: ceramics, metals, minerals, glasses, minerals, multi-phase materials,
composites etc.

Ion polishing system PIPSI
Platform: Electron Microscopy Platform (PMEL).
Contact: Anne-Marie BLANCHENET.
PIPSI is a ion polishing machine that works by ion thinning at a very small angle (between 0 and 10 °). The low spray angles have the advantage of minimizing the damage caused by irradiation and beam heating while at the same time producing samples with electron-transparent areas with minimal artefacts. Ability to work at low temperatures.
Applications:
TEM preparation for many materials: ceramics, metals, minerals ...

Ion polishing system GATAN DUO MILL
Platform: Electron Microscopy Platform (PMEL).
Contact: Anne-Marie BLANCHENET.
The GATAN DUO MILL 600 DIF model is used for the final stage of sample preparation for transmission electron microscopy. The sample is thinned on both sides by means of an argon ion beam.
The acceleration voltage, the ionic current and the angle of incidence varying from 0 to 40 ° can be selected according to the properties of the sample material. Pre-thinned samples are bombarded until perforation or until the sample becomes electron-transparent. Ability to work at low temperatures for fragile materials.
Applications:
Thin slimming and large area of thinning for ceramics, metals, minerals

Metals coated machine: Precision Etching and Coating System (PECS)
Platform: Electron Microscopy Platform (PMEL).
Contact: Anne-Marie BLANCHENET.
PECS deposits extremely thin metal coatings on samples for both SEM and TEM observations.
The target material is bombarded by two argon ion beams accelerated to about 8 kV.
The ejected target material then strikes the surface of the sample which is rotated at different angles
during the coating process. The thickness of the deposit can be controlled.
Application: Coated of chrome deposit, carbon, platinum ...
