Chapter 4: Power and particle control

Richard Pitts

Progress, since the ITER Physics Basis publication (ITER Physics Basis Editors et al 1999 Nucl. Fusion 39 2137-2664), in understanding the processes that will determine the properties of the plasma edge and its interaction with material elements in ITER is ...

Plasma wall interaction and its implication in an all tungsten divertor tokamak

Yves Martin, Alexandre Schmid, Marco Wischmeier, Alberto Bottino, Andrea Scarabosio, Dávid Wágner, Heinz Mueller, Hartmut Zohm, Emanuele Poli, Adriano Manini, Giovanni Tardini

ASDEX Upgrade has recently finished its transition towards an all-W divertor tokamak, by the exchange of the last remaining graphite tiles to W-coated ones. The plasma start-up was performed without prior boronization. It was found that the large He conten ...

Observation of Spontaneous Toroidal Rotation Inversion in Ohmically Heated Tokamak Plasmas

Basil Duval, Antoine Pochelon, Andrea Scarabosio, Alessandro Bortolon

Bulk plasma toroidal rotation is observed to invert spontaneously from counter to cocurrent direction in TCV (Tokamak à Configuration Variable) Ohmically heated discharges, in low confinement mode, without momentum input. The inversion occurs in high curre ...

Ohmic H-mode discharges in the Tokamak Configuration Variable (TCV) have recently been heated for the first time by electron cyclotron (EC) waves at the 3rd harmonic (X3) at full power. New edge localized mode (ELM) behaviour has been found, with larger am ...

Results are presented from the JET Trace Tritium Experimental (TTE) campaign using minority tritium (T) plasmas (n(T)/n(D) < 3%). Thermal tritium particle transport coefficients (D-T, nu(T)) are found to exceed neo-classical values in all regimes, except i ...

ELMy H-mode experiments at JET in 2000/mid-2002 have focused on discharges with normalized parameters for plasma density, energy confinement and beta similar to those of the ITER Q(DT) = 10 reference regime (n/n(GW) similar to 0.85, H-98(y,H-2) similar to ...
