Detailed distribution of AC loss in the NET TF coil

Conference · · IEEE Trans. Magn.; (United States)
OSTI ID:6006670

The AC loss in the NET (Next European Torus) TF coil has been computed as a function of space and time using a field map of the DC toroidal field components and AC poloidal field components for three proposed conductor designs. Resolving the field B, field change ..delta..B and field derivative B into components transversal and parallel to the conductors, the value of the coupling, eddy currents and hysteresis losses was computed using a set of simplified expressions. The calculation performed on the whole coil is presented here using the distributions along a developed pancake of the instantaneous and average values of AC loss.
