3.4.1 Installation and testing of ITER CS<br />
and TF model coils (ITER Task M20)<br />
The central solenoid model coil (CSMC) was<br />
extensively tested in static and pulsed regimes in the<br />
first half of 2000. All the main goals of the testing<br />
program were achieved and the results presented at<br />
the major conferences [3.5-3.11].<br />
The coil then became a large testing facility in which<br />
samples of different types of conductors (40 – 90 m<br />
long) have already been tested (CS insert in 2000,<br />
toroidal field (TF) insert in 2001) or will be tested<br />
(Nb-Al insert in 2002, poloidal field (PF) insert in<br />
2003) in static or variable fields (up to 13 T).<br />
The main contribution of <strong>ENEA</strong> to data analysis<br />
concerned the study of AC losses, particularly a<br />
quantitative determination of the continuous<br />
decrease in the coupling losses in the conductor<br />
during the test campaign. This phenomenon had<br />
already been observed during the tests of an ITERrelevant<br />
coil at the <strong>ENEA</strong> laboratories [3.12].<br />
The toroidal field model coil (TFMC) (fig. 3.7) was<br />
installed in the TOSKA facility at
