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
