On the very high energy confinement observed in super H-mode DIII-D experiments
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Analysis of recent super H-mode experiments on DIII-D shows that high rotation, not high pedestal, plays the essential role in achieving very high conﬁnement H98y2 > 1.5. Very high conﬁnement is reached early on in the H-mode phase of these discharges, when the pedestal is still very low, but after the toroidal rotation has already built-up to very high levels in the core. As the discharge evolves, the rotation drops, and so does the energy conﬁnement, despite a sustained very high pressure pedestal. During this evolution, the conﬁnement quality is linearly correlated with the core toroidal rotation, which varies according to diﬀerent levels of injected neutral beam torque per particle. Core transport modeling shows that the contribution from rotation in the E×B shear is responsible for conﬁnement quality signiﬁcantly in excess of stand' .
