Error Fields computation in the RFX-mod2 Reversed field Pinch

An accurate control of the magnetic boundary ofa thermonuclear plasma is an important issue in magnetic confinement research. The development of methods for the active control of magnetohydrodynamic instabilities and correction oferror fields is mandatory. A substantial modification of the layoutof the RFX-mod device is in progress: the aim of this paper isto assess the potential advantages of the proposed solution with advanced numerical techniques based on integral formulations.
