conclusions

• Huge amount of work!
• almost all Tokamaks involved lot of labs for
  analysis
• all topics covered even if
• in situ diagnostics not enough covered!
• removal tools not yet tested!
• 2009
• dust characterisation (SEM, Focussed Ion Beam,
  EDX)
• AUG, JET, CEA, VR, FZJ, UKAEA
• dust diagnostics
• erosion, electrostatic grids, IR measurements,
  CCD
• impacts events, injection of dust, spectroscopy
  of dust
• JET, IPP, FTU, CIEMAT, FZJ, UKAEA, VR, CEA
• dust suspension and recovery (CEA)
