  Welcome and introduction to WP PWIE
  
  Speaker: Sebastijan Brezinsek (FZJ)

  Overview of SP B and SP B.4 in 2021
  
  Speaker: Antti Hakola (TEKES / VTT)

  ENEA activities in 2021: W-based coatings with pre-defined properties (incl. SEM, AFM, TDS characterization) produced for analyses and plasma experiments – plans and capabilities
  
  Speaker: Matteo Passoni
  columnar and porous W layers produced in FP8 --> morphology and grain size can be varied
  
  multilayer structures to mimic re-deposits --> GyM, (MAGNUM, PSI-2, others)
  
  rough and/or patterned surfaces --> also more complex structures can be produced --> GyM and/or tokamaks
  
  Francesco: TDS available (size limit as in the past)
  
  Cedric: interested in Raman analyses of pyramid structures
  
  Sebastijan: MAGNUM experiments on re-deposited W --> one wants to produce proxies to those
  
  Eduardo: what structures can be produced? Different aspect ratios of structures, chemical etching
  
  Focus in 2021 on homework of re-deposits and production of various morphologies for GyM
- 4
  IAP activities in 2021: Be-based coatings with pre-defined properties (incl. SEM, XRD, GDOES, TDS characterization) produced for analyses and plasma experiments – plans and capabilities
  
  Speaker: Corneliu Porosnicu
  
  SPB.4_IAP_Porosnicu_180621.pdf
  Be films: mixtures, sample heating, baking simulations, gas inclusions, roughness
  
  Analysis capabilities: SEM, XRD, TDS
  
  Sebastijan: LID-QMS, LIBS request for samples --> discussions with Hennie needed; low-temperature peak, can it be due to BeDx? Or rather sample instability? Test samples by Raman if that really is BeDx --> one clear focus point! (temperature dependence!?)
  
  Cedric: high-temperature peaks, due to contamination? or other elements in the sample structure, may also be multitude of defects?
  
  Distinguish between trapping and de-trapping due to evaporation by TDS!
  
  Focus on understanding the data from samples and only produce samples for LIBS, combine the work with what we have learnt from JET --> involve Jari in the discussions --> action on AH
- 5
  IAP activities in 2021: W-based coatings with pre-defined properties (incl. SEM, XRD, GDOES, TDS characterization) produced for analyses and plasma experiments – plans and capabilities
  
  Speaker: Eduard Grigore
  
  SPB.4_IAP_Grigore_180621.pdf
  New W-based coatings: vary the grain size (=morphoplogy)
  
  Experiments in GyM? Comparative studies would be of interest --> action on AH
  
  Cedric: Ne and He release from samples? Trapping mechanisms? Are there bubbles around or something else --> send samples to CEA for further analyses --> action on AH to check the status
  
  Bobi: collaboration with Edi --> action on Bobi and Edi to discuss
- 6
  CEA activities in 2021: Raman, SEM, and CLSM characterization of selected Be and W reference samples – plans and capabilities
  
  Speaker: Cedric Pardanaud
  
  SPB.4_CEA_Pardanaud_180621.pdf
  Confocal and Raman capabilities: CLSM for large surfaces (witth varying roughnesses), SEM and FIB also available --> identify what is under the surfaces
  
  Raman useful for Be, BeD, BeO, WO, trapped D2
  
  Interested in H-containing samples to detect BeH/BeD formation --> action on Bobi
  
  Bobi: fatty acids found on some samples --> contamination to be clarified
  
  Jari: any other samples than JET limiter ones? --> wall probes to be studied! --> action on Jari
- 7
  CIEMAT activities in 2021: SEM and SIMS characterization of selected W reference samples – plans and capabilities
  
  Speaker: Daniel Alegre Castro (CIEMAT)
  
  kick-off_WPPWIE_SPB4_CIEMAT.pdf
  SEM and SIMS in 2021 for selected samples
  
  Next step: compare the results to those measured at VTT --> action on AH
  
  Decide on next steps afterwards
- 8
  IST activities in 2021: RBS and NRA characterization of selected Be and W reference samples – plans and capabilities
  
  Speaker: Rodrigo Mateus
  
  SPB.4_IST_Mateus_180621.pdf
  Ne-containing Be samples: Ne can be seen
  
  Implantation of W samples, to be clarified to which extent they are needed
  
  Extend implantation to Be samples and additional W samples --> additional data for TDS studies to check which trapping mechanisms are active
- 9
  
  JSI activities in 2021: TDS, XPS, and XRD characterization of selected Be and W reference samples – plans and capabilities
  
  Speaker: Vincenc Nemanic
- 10
  RBI activities in 2021: ERDA and PIXE characterization of selected Be and W reference samples – plans and capabilities
  
  Speaker: Ivancica Bogdanovic Radovic (RBI)
  
  SPB.4_RBI_Iva_180621.pdf
  can analyze also fatty acids, new installation dual beam irradiation facility
  
  rough samples problematic for TOF-ERDA; also W and Ta cannot be separated
- 11
  VTT activities in 2021: RBS, NRA, ERDA, LIBS, and SIMS characterization of selected Be and W reference samples – plans and capabilities
  
  Speaker: Antti Hakola (TEKES / VTT)
  
  SPB.4_VTT_Hakola_180621.pdf
  SIMS quantification, what samples what is needed --> also Eduardo is interested --> action on AH and Jari to organize a separate meeting
  
  Think about wishlist from Eduardo and Rodrigo, reference samples also!
- 12
  Discussion on tasks and identification of gaps
  Action on AH to prepare an addendum to old Master Excel on needs for samples
  
  Waiting for the results of the SP X kick-off meeting (LIBS community)
  
  A proper Master Excel to be prepared for 2022 campaign

  Needs for analyses/measurements in other labs
