D retention and material defects probed using Raman microscopy in JET limiter samples and beryllium-based synthesized samples
C Pardanaud, M Kumar, P Roubin +12
We report on the detection by means of Raman spectroscopy of amorphous beryllium deuteride, BeD 2 , in magnetron sputtered deposits synthesized in two different laboratories and co…
Post-mortem analysis of tungsten plasma facing components in tokamaks: Raman microscopy measurements on compact, porous oxide and nitride films and nanoparticles
Cédric Pardanaud, David Dellasega, Matteo Passoni +16
Raman microscopy is one of the methods that could be used for future post-mortem analyses of samples extracted from ITER plasma facing. This study shows that this technique is usef…
Diagnostics of low-pressure hydrogen discharge created in a 13.56 MHz RF plasma reactor
J Krištof, A Annušová, M Anguš +5
A 13.56 MHz RF discharge in hydrogen was studied within the pressure range of 1-17 10 Pa, and at power range of 400-1000 W. The electron energy distribution function and 18 electro…
Forming Weakly Interacting Multi Layers of Graphene by using Atomic Force Microscope Tip Scanning and Evidence of Competition Between Inner and Outer Raman Scattering Processes Piloted by Structural Defects
C. Pardanaud, A. Merlen, K Gratzer +8
We report on an alternative route based on nanomechanical folding induced by AFM tip to obtain weakly interacting multi-layer graphene (wi-MLG) from a chemical vapor deposition (CV…
Thermal stability and long term hydrogen/deuterium release from soft to hard amorphous carbon layers analyzed using in-situ Raman spectroscopy. Comparison with Tore Supra deposits
C. Pardanaud, C. Martin, G. Giacometti +3
The thermal stability of 200 nm thick plasma enhanced chemical vapor deposited a-C:H and a-C:D layers ranging from soft to hard layers has been studied and compared to that of depo…
Raman microscopy as a defect microprobe for hydrogen bonding characterization in materials used in fusion applications
Cédric Pardanaud, Younès Addab, Céline Martin +6
We present the Raman microscopy ability to detect and characterize the way hydrogen is bonded with elements that will be used for ITER's plasma facing components. For this purpose…
Long Term H-Release from Amorphous Carbon Evidenced by in Situ Raman Microscopy under Isothermal Heating
Cedric Pardanaud, C. Martin, G. Giacometti +6
We study the kinetics of the H release from plasma-deposited hydrogenated amorphous carbon films under isothermal heating at 450, 500 and 600 {\degree}C for long times up to severa…
Raman spectroscopy investigation of the H content of heated hard amorphous carbon layers
Cedric Pardanaud, C. Martin, P. Roubin +4
We revisit here how Raman spectroscopy can be used to estimate the H content in hard hydrogenated amorphous carbon layers. The H content was varied from 2 at.% to 30 at.%, using he…
Raman micro-spectroscopy as a tool to measure the absorption coefficient and the erosion rate of hydrogenated amorphous carbon films heat-treated under hydrogen bombardment
Cedric Pardanaud, E. Aréou, C. Martin +6
We present a fast and simple way to determine the erosion rate and absorption coefficient of hydrogenated amorphous carbon films exposed to a hydrogen atomic source based on ex-sit…
Raman study of CFC tiles extracted from the toroidal pump limiter of Tore Supra
Cedric Pardanaud, G. Giacometti, C. Martin +10
The structure of six tiles extracted from the erosion and deposition zones (thin and thick deposition) of the Tore Supra toroidal pump limiter (TPL) have been analysed in the frame…
Characterisation of carbon dust produced in sputtering discharges and in the Tore Supra tokamak
Cécile Arnas, Claire Dominique, Pascale Roubin +3
The sputtering of inside wall components of tokamaks can lead to the injection of supersaturated vapour in the plasma edge. The resulting condensation favours the formation of clus…
