AC losses for the prototype cable-in-conduit conductors for NET

The AC losses requirement for the superconducting coils of the Next European Torus (NET) project are discussed on the basis of the pulsed field scenario and plasma disruptions. The AC losses test results on the prototype 40 kA cable-in-conduit superconductors developed for NET are presented. The performance achieved is compared with the target. Some recommendations are made for work to be done.<>
