Additional analysis to do on LOTUS data:

Alcator C-MOD has compared plasma performance with plasma-facing components (PFCs) coated with boron to all-metal PFCs to assess projections of energy confinement from

Work on the H-mode has included studies of local threshold con- ditions and comparisons with theory, demonstration of regimes with good confinement but no large, potentially

The strong co-current toroidal rotation in enhanced D ␣ 共 EDA 兲 high confinement mode (H-mode 兲 plasmas is observed to propagate in from the edge on a time scale similar to the

Figure 5: Left: Wavenumber spectrum of L-mode density uctuations; power-law ts to the 3 smallest and 5 largest wavenumbers is also shown, right: H-mode wavenumber spectrum

Alcator c-mod has compared plasma performance with plasma facing components ( pfc s) coated with boron to all-metal pfc s to assess projections of energy confinement from

The left-hand plot shows the global behaviour up to high frequencies; the attached phase uctuations (thick solid line) have two components (as L-mode), a large amplitude low

Figure 8.42 shows Mirnov coil measurements of magnetic fluctuations for a discharge experiencing a slow transition from good to bad confinement.. The lines on the spectrogram are due

• Band and Mirnov correlations for good/bad confinement shots; current ramps (PoP)..
