Challenges and Solutions in the Design of RFX-Mod2, a Multiconfiguration Magnetic Confinement Experimental Device

A number of modification s and enhancements are underway on the RFX - mod Reversed field Pinch (RFP) device . The main scientific goals motivating the modifications are the improvement of the confinement in the R eversed F i e l d P inch configuration and the investigation of a broad spectrum of plasma physics topics , through the exploitation of the multi configuration capability of the device, which can be operated as a RFP, ultra low q, circular and shaped tokamak . This paper describes the major challenges tackled to design technical solutions able to achieve this scientific mission.
