Advanced Spectroscopic Analyses on a:C-H Materials: Revisiting the EELS Characterization and its Coupling with multi-wavelength Raman Spectroscopy
L. Lajaunie, C. Pardanaud, C. Martin +4
Hydrogenated amorphous carbon thin films (a:C-H) are very promising materials for numerous applications. The growing of relevance of a:C-H is mainly due to the long-term stability…
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…
