ICRF Heating at JET: From Operations with a Metallic Wall to the Long Term Perspective of a DT Campaign
The first series of experiments with the ITER-Like Wall (ILW) will start mid-2011 with D plasmas and will continue through 2012-13 with H, 4He and D plasmas, and up to 2014-15, when a DT campaign is proposed. In this paper, the previous experience at JET is reviewed to set the scene for the future challenges of ICRF operation including change in the ICRF coupling, W impurity production and evaluation of localized power loads due the RF sheaths. development in a Beryllium/Tungsten environment of ICRF heating schemes for the non activated and the DT phases of ITER.
