Microscopy Analyses of Fusion Devices Samples in 2021
"Explore the microscopy studies and characterization of samples from fusion devices like AUG, WEST, and W7-X in 2021. Learn about the ongoing work, sample details, techniques used, and new samples for analysis, including surface modifications and co-deposits. Kick-off meeting details and tasks for plasma-exposed materials characterization. Availability of samples for analysis and potential inclusion of new samples in the 2021 program."

SPB2&B3: IPPLM activities in 2021: microscopy analyses of AUG, WEST, W7-X and reference samples plans and capabilities El bieta Fortuna-Zale na, IPPLM (WUT)
B2 2021 tasks B2 Material migration in toroidal devices Task: Microscopy studies of marker samples and other samples from specific plasma experiments (AUG, WEST, W7-X) D9: SEM, TEM and FIB characterization of selected samples from experiments on AUG, WEST, and W7-X WP PWIE SP B.2 & SP B.3: Kick-off meeting| 11 June 2021 | Page 2
W7-X samples. Work ongoing. Two target elements HM19TM400hTE, HM19TM400hTE2, W7X OP1.2b campaign (all together over 50 samples). HM19TM400hTE1 target element. Sample size: for samples P2 P22, 25 x 55 mm, the thickness of the samples of around 10 mm. The aim of the work: (i) assess surface modification of the material caused by the plasma wall interactions (erosion/deposition pattern), (ii) study the co-deposits formed and (iii) analyze the dust particles found. Techniques used: SEM, EDS, TEM and STEM. WP PWIE SP B.2 & SP B.3: Kick-off meeting| 11 June 2021 | Page 3
WEST samples. Work ongoing. 3 samples cut from the erosion marker tile 941G142 (outer#22) C1+C2+C3; designated as C3-22oF, C3-22oH and C3-22oK. WP PWIE SP B.2 & SP B.3: Kick-off meeting| 11 June 2021 | Page 4
Samples from FTU and AUG No samples from AUG experiments. What is availability of erosion/migration samples for analyses? New FTU sample received for analysis this year from Marco De Angeli. Could this work be included into 2021 programme? WP PWIE SP B.2 & SP B.3: Kick-off meeting| 11 June 2021 | Page 5
B3 2021 tasks B3 Characterization of plasma-exposed materials Task: Determine surface changes on selected WEST PFUs and reference coatings from plasma exposures in MAGNUM-PSI, PSI-2, and GyM D3: SEM, TEM and FIB characterization of selected WEST PFUs and plasma-exposed reference samples WP PWIE SP B.2 & SP B.3: Kick-off meeting| 11 June 2021 | Page 6
Samples after experiments in MAGNUM- PSI 2 samples from January 2020 exposure: IU 672-6 W D/(6%N) (high flux) loading EU2_30-3 W/Ta D/(6%N) (high flux) loading What is availability of new samples from MAGNUM-PSI, PSI-2? Should I contact Matteo Passioni/David Dellasega for GyM samples? (We are not any more in the same work package). WP PWIE SP B.2 & SP B.3: Kick-off meeting| 11 June 2021 | Page 7
