“…In this work a different system to adjust the ripple amplitude has been evaluated by using Finite Element Models with the Maxwell EM code. This system is based on active poloidal coils placed between plasma and TFCs, fed with a current in the opposite direction respect to those in the TFCs [4]. A preliminary model of these coils has been drawn and integrated with the full CATIA5 CAD model of the FAST machine (Fig.…”

“…Nevertheless, this solution could produce the appearance of a TFR with opposite sign when operating at lower toroidal field, as is widely foreseen in FAST. A conceptual study was then performed to analyze the option to realize an active control of the ripple amplitude [20] by mean of proper coils located outside the VV in front of any TFC and fed with a current in the opposite direction respect to the TFC current. The maximum current foreseen for these coils is the same foreseen for the TFC system, simplitying then the power supply and feeding issues.…”

FAST (Fusion Advanced Studies Torus) is a p ro p osal for a Satellite Facility which can contribute the ra p id ex p loitation of ITER and p re p are ITER and DEMO regimes of o p eration, as well as ex p loiting innovative DEMO technology. FAST o p erates with high p erformance H-Mode (BT up to 8.5 T; Ip up to 8 MA) as well as Advanced Tokamak o p eration (Ip=3 MA), and full non inductive current scenario (Ip=2 MA) [1). The p roject is based on a dominant 30 MW of ICRH, 6 MW of LH and 4 MW of ECRH. Helium gas at 30K is used for cooling the resistive co pp er magnets, which dimensions have been determined to limit the coil tem p erature at the end of the longest p ulses ( p ulse length u p to 170 s). The p eak current density in the reference H-mode is about 45 MA/m 2 • The Finite Element Method (FEM) has been em p loyed to analyse the stresses of the load assembly structure (2) using the ANSYS code. Due to the full structural coo p eration, the Toroidal Field Coils, Central Solenoid and mechanical structure, have been modelled as a whole, using mechanical and thermal smeared p ro p erties. Structural analyses were p erformed at the most significant times of the o p erating scenario. The FW consists of a bundle of coaxial tubes armoured with 4
