Abstract

The FTU machine was designed to operate with circular plasma. A modification of the FTU (FTU-D) load assembly has been studied in order to allow operation with strongly shaped plasmas (R=1 m, a=0.19-0.22 m, elongation k=1.6, triangularity δ=0.8). The scientific aim of this proposal is the investigation of the so called advanced tokamak operation characterised by the simultaneous achievement of high-β and high bootstrap current fraction in regimes with high energy confinement achieved by current profile control
