Modelling

Modelling

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)
