Detailed electromagnetic numerical evaluation of eddy currents induced by toroidal and poloidal magnetic field variation and halo currents
TL;DR: In this paper, a detailed analysis of the EM loads in the ITER divertor during plasma disruptions is mandatory for the correct dimensioning of the divertor component, which is mainly produced by: (1) toroidal flux variation (TFV) during the thermal quench (TQ) and current quench(CQ); (2) halo currents (HC); and (3) poloidal flux variations (PFV), during TQ and CQ phase.

TL;DR: In this paper, the possibility of using liquid lithium as plasma facing component for the divertor target plates was investigated on FTU by employing an innovative solution that exploits the surface tension forces in capillary channels to compensate j ǫ×B forces induced in lithium.

The ITER TF coil ripple: Evaluation of ripple attenuation using Fe insert and of ripple enhancement produced by TBM
TL;DR: In this paper, an accurate evaluation of the toroidal field ripple in ITER has been carried out by finite element models including the presence of the 18 TF coils and a set of ferromagnetic inserts that aim to lower the field ripple well below 1%.
