U.S.- and China-based magnetic fusion scientists in the control room of the DIII-D tokamak in San Diego. Inset: Almost identical electron temperature profiles (shown in top plot versus the normalized radial coordinate with the blue(red) line representing the low(high) rotation case) are produced in the experiments with both high and low rotation DIII-D plasmas (toroidal rotation velocity from these discharges shown in the bottom plot with the same color assignment). Both discharges have very high confinement.
