From: Novel concept suppressing plasma heat pulses in a tokamak by fast divertor sweeping
(a) Oscillation circuit of the swept coil. The current \(I_\mathrm {coil}\) (directly proportional to the strike point position) oscillates during 2 subsequent ELMs. Charging after each even ELM suppresses the coil mechanical vibrations down to 0.1 mm due to heavy coil inertia (explained in Section 5 in43). (b) Sketch of 45 mm thick Litz conductor sustaining of twisted 0.25 mm thin wires without isolation. Such a cable suppresses the skin-effect, passing thus 1 kHz AC currents with resistivity near its DC value. Let a cooling pipe be located in the central empty space.
