ITER TF coil double pancake assembly: Laser welding numerical simulation

DTT - Divertor Tokamak Test facility: A testbed for DEMO

“…The DTT magnetic system [14][15][16][17][18][19][20], shown in Fig. 4, includes • 2 in-vessel up-down symmetric copper coils independently fed for the control of the vertical unstable mode and the implementation of a fast radial control of the plasma centroid; • 4 divertor in-vessel copper coils for the local modifications of the magnetic configuration in the divertor region and the implementation of power exhaust feedback control strategies.…”

“…Further details on the main components as well as on the additional systems can be found in [6] and in [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. In particular, the relevant additional subsystems include the First Wall [6]; the Shield and Cryostat [6]; the Data Acquisition, Diagnostics and Control Systems [10][11][12][13]; the Remote Handling [28]; the Cooling and Shielding Systems [23]; the Pumping and Fuelling Components [6]; the Auxiliary Systems [6].…”

“…All these aspects are discussed in detail in the following sections. The status of the project, its strengths and weaknesses, the European and international meaning of the initiative, have been discussed in detail the DTT Interim Design Report [6] and in recent papers and posters presented in the Virtual Edition of SOFT 2020 [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Therefore, this paper is not intended to be exhaustive.…”

Thermal analysis of laser welding for ITER correction coil case

“…Most of the welding simulation research is for the conventional welding methods (TIG, MIG), while some authors also simulated laser welding processes [10][11][12][13][14].…”
