Final Design of ITER In-Vessel Coils and Manufacturing of In-Vessel Coil Conductor
/ Encheva, Anna (ITER) ; Bontemps, Vincent (ITER) ; Fichera, Claudio (ITER) ; Laquiere, Julien (ITER) ; Macioce, Davide (ITER) ; Mariani, Nicola (ITER) ; Piccin, Roland (ITER) ; Tronza, Vladimir (ITER) ; Vostner, Alexander (ITER) ; Sgobba, Stefano (CERN)
Following a decision made at the ITER Council in November 2013, two types of in-vessel coils (IVCs), namely, edge-localized mode (ELM) coils to mitigate ELMs and vertical stability (VS) coils to provide vertical stabilization of the plasma, have been incorporated in the ITER baseline design. The in-vessel environment is severe, characterized by large transient electromagnetic fields, high radiation flux, and high temperature. [...]

Performance of the Cable-in-Conduit Conductors for Super-X Test Facility
/ Dai, Chao (Hefei, Inst. Plasma Phys.) ; Wu, Yu (Hefei, Inst. Plasma Phys.) ; Shi, Yi (Hefei, Inst. Plasma Phys.) ; Sedlak, Kamil (Ecole Polytechnique, Lausanne) ; Bajas, Hugo (Ecole Polytechnique, Lausanne) ; Nijuis, Arend (Twente U., Enschede) ; Hao, Qiangwang (Hefei, Inst. Plasma Phys.) ; Han, Houxiang (Hefei, Inst. Plasma Phys.) ; Liu, YunHao (USTC, Hefei) ; Devred, Arnaud (CERN) et al.
Following the conceptual design, the engineering design of the dc magnet and cable-in-conduit conductor (CICC) for the Super-X test facility has been done in 2021. Totally three types of conductors with different structures were designed for the three pairs of coils in the dc magnet, respectively. [...]

Efficient Combination of Surface Texturing and Functional Coating for Very Low Secondary Electron Yield Surfaces and Rough Nonevaporable Getter Films
/ Himmerlich, Marcel (CERN) ; Zanin, Danilo A (CERN) ; Taborelli, Mauro (CERN) ; Granadeiro Costa, Angelo Rafael (CERN) ; Costa Pinto, Pedro (CERN) ; Lain Amador, Lucia (CERN) ; Vollenberg, Wilhelmus (CERN) ; Baris, Adrienn (CERN) ; Garcia‐Tabares Valdivieso, Elisa (CERN ; Carlos III U., Madrid) ; Perez Fontenla, Ana Teresa (CERN) et al.
The formation of a fissured copper surface by picosecond pulsed laser irradiation is combined with functional coatings consisting of Ti and amorphous carbon layers or a Ti–Zr–V compound film to fabricate surfaces with the maximum of the secondary electron yield being as low as 0.4. By structural and spectroscopic analysis of the formed surfaces it is demonstrated that both coatings enclose the nanostructures generated by redeposition of metal structures from the laser-induced plasma plume, keeping the initial topography intact.
