Goldston scaling for different currents) <strong>and</strong> H-mode (curves are 2 x Goldston scaling) cases.<br />

9. Confinement <strong>and</strong> Transport<br />

The global confinement times, defined as TE = W/(P-dW/dt), are shown in<br />

Fig. 15 as a function of input power for both the l^mode <strong>and</strong> H-mode case. These<br />

results can be equally well represented by the Goldston power law [131 :<br />
