Active control of edge localized modes with a low n external perturbation fields in the JET tokamak
Active control of edge localized modes with a low n external perturbation fields in the JET tokamak
Active control of edge localized modes (ELMs) by using static external magnetic perturbation fields with low toroidal mode number, n, has been demonstrated for both, ITER baseline (q(95) similar to 3) and high beta advanced tokamak scenarios at the JET tokamak. During the application of the low n fi...

Active control of edge localized modes (ELMs) by using static external magnetic perturbation fields with low toroidal mode number, n, has been demonstrated for both, ITER baseline (q(95) similar to 3) and high beta advanced tokamak scenarios at the JET tokamak. During the application of the low n field the ELM frequency increased by a factor up to similar to 4-5. Reduction in carbon erosion and ELM peak heat fluxes on the divertor target by roughly the same factor as the increase of the ELM frequency has been observed. The frequency of the mitigated ELMs using a low n field is found to increase proportional to the total input heating power. Compensation of the density pump-out effect observed when the external low n held is applied has been achieved by gas fueling in low triangularity plasmas. (C) 2009 Published by Elsevier B.V. |
