Implementation of an ITER-relevant QP-based Current Limit Avoidance algorithm in the TCV tokamak
D. Frattolillo, A. Mele, C. Galperti +11
The problem of avoiding saturation of the coil currents is critical in large tokamaks with superconducting coils like ITER. Indeed, if the current limits are reached, a loss of con…
Observation of confined current ribbon in JET plasmas
E. R. Solano, P. J. Lomas, B. Alper +29
we report the identification of a localised current structure inside the JET plasma. It is a field aligned closed helical ribbon, carrying current in the same direction as the back…
Real-time identification of the current density profile in the JET Tokamak: method and validation
Didier Mazon, Jacques Blum, Cédric Boulbe +6
The real-time reconstruction of the plasma magnetic equilibrium in a Tokamak is a key point to access high performance regimes. Indeed, the shape of the plasma current density prof…
Developement of real time diagnostics and feedback algorithms for JET in view of the next step
A. Murari, E. Joffrin, R. Felton +15
Real time control of many plasma parameters will be an essential aspect in the development of reliable high performance operation of Next Step Tokamaks. The main prerequisites for…
