| Description: | Modulate the plasma current Ip to indirectly modulate the edge current above/below the peeling limit | ||
| Experimental Approach/Plan: | Pre-program oscillating plasma current. | ||
| Background: | Similar to proposal #434, except that the modulation in the edge current is not induced by the I-coils, but by the E-coil. This will cause a modulation of Ip and of the whole current profile. The shape of the current profile will also be modulated. The effect at the edge will be an oscillation of the local current density. Probably the edge pressure gradient will fluctuate too. | ||
