  Be dust formation – plans for 2023 and comparison against JET-ILW results
  
  Minutes
  
  Speaker: Corneliu Porosnicu (IAP)
  
  Kick-off Be dust - 2023 (2).pptx
  Proposal for using new arcing-type of device for producing Be dust inside crucibles and analysis of the produced dust afterwards --> relies on brushing the crucible for dust accumulated on the surfaces
  
  Controlled scanning of the parameter space to see what is critical in producing dust as at JET-ILW or why in JET so little dust is produced after all --> what is the physics reason for this?
  
  Recommendations to use also Si collector wafers, mounted on the crucible walls
  
  Analysis programme of the dust samples to be defined afterwards --> RBI already committed to performing some part of the measurements within the PMs allocated to them under SP B.2/SP B.3
  
  In 2024, proceed to more complex conditions, e.g., considering the role of pure sputtering, melting etc. besides arcing
  
  Check the status of the task in May

  W dust formation – plans for 2023 and comparison against DEMO safety case
  
  Minutes
  
  Speakers: Gheorghe Dinescu (IAP), Tomy Acsente
  
  KOM SPB5 Acsente T W dust -march 2023.pdf
  Study the production of W dust particles in D2 - and assess the role of different parameters on the production rate and the properties of the dust particles (e.g., applied energy, amount of Ar added etc.)
  
  In 2024, the studies can be expanded to arcing-type of sources, making possible to compare the outcomes of Be and W tasks
  
  Progress of the task to be followed up in May-June

  Hypervelocity dust impacts – plans for 2023
  
  Minutes
  
  Speaker: Dr Marco De Angeli (ENEA-CNR Milan)
  
  KoM 2023 SPB_5 Dust ENEA.pdf
  Expose W or W+O co-deposits into hypervelocity dust beam --> properties of the co-deposits to be agreed on in the SP B.1&SP B.4 kick-off meeting on Friday
  
  Analysis programme of the exposed samples to be agreed later on --> depend on what we see, can consider here RBI (for compositional analyses) and IPPLM (additional microscopy)
  
  In 2024, can consider also W+O+D2 samples and investigate (e.g., using TDS) how D2 content changes upon exposure
  
  To be followed up in June-July

  Dust investigations on AUG and WEST – 2023 plans
  
  Minutes
  
  Speakers: Martin Balden (IPP), Volker Rohde
  
  Rohde_PWIE_SP_b5_Kick_IPP.pdf
  Focus in 2023 on the AUG dust samples and their analyses and trying to get an idea of the main dust production mechanisms --> extrapolation only to happen in latter years
  
  WEST samples mainly handled by CEA --> can refer to the published data in a PhD dissertation
  
  Additional analyses from C5 samples can also be made for the characteristics of dust on them --> e.g., IPPLM is interested
  
  To be followed-up in June-July
