On the possibility of creating doublet-shaped plasmas in TCV
Recently, the doublet has received renewed interest because it has an intrinsic zone of negative shear, which is tied to the magnetic configuration and does not depend on a hollow current profile. Negative magnetic shear is thought to have beneficial effects on plasma confinement in tokamaks. Another important property of doublets is the fact that vertical instability growth rates are much lower than in D-shaped plasmas with the same overall elongation. In this paper, we consider 3 different scenarios for creating doublets and we summarize initial experimental work in this field on TCV.
