Popis: An innovative divertor concept, the Fish Tail Divertor, is proposed in this paper, aiming at reducing the peak heat load on the tokamak divertor plate as well as that due to the edge localized modes. This new concept has been implemented in experiments to demonstrate its capability of strike point sweeping on the plate at the frequency range from ten to one hundred Hz by using an oscillating magnetic field. The strike point movement of 5-6 cm is achieved by applying a coil current of several percent of plasma current, leading to a significant reduction of heat load on the divertor target plate. The result indicates a possible application in a fusion reactor.
