The ITER toroidal field model coil (TFMC)

The ITER toroidal field model coil project

“…The TFMC and its test arrangement were designed to be representative for the ITER TF coil in respect of layout and electrical and mechanical stresses [24][25][26][27]. The layout of the TFMC overtook as many as possible features of the ITER TF coil design on a scale nearly 1:1.…”

“…3.1) with a circular Nb 3 Sn cable in conduit conductor placed into the spiral grooves of the 316LN stainless steel (SS) radial plates required the development of new manufacturing methods including the associated tooling. This has been described in several publications [30][31][32][33][34]. The design, manufacture and quality assurance (QA) results are described in detail in [35].…”

Development of superconducting and cryogenic technology in the Institute for Technical Physics (ITP) of the Research Center Karlsruhe

“…The test configuration selected has been placement of the ITER TFMC adjacent to the EURATOM LCT coil, linked by a suitable intercoil structure. For current levels of 70 kA (80 kA) in the TFMC and 16 kA, in the LCT, a maximum magnetic field of 8.8 T (9.7 T) can be achieved [34].…”

Superconductors for fusion magnets: realizations, prototypes and running projects

“…The stored energy is 641 MJ, compared with 13 GJ in the full-size central solenoid. The TF model coil [19] is a pancake-wound, race-track coil to be assembled with the LCT-EU coil and tested up to 70 kA, 8.8 T. The mass of the TF model coil is 31 t, compared with 700 t for a full-size TF coil. Both coils use the Nb 3 Sn cable-in-conduit conductors designed for the full-size coils; see figure 1.…”
