FIG. 4. (a) Panicle confinement lime from limiter probe measurements as a function of ne in He discharges.<br />

[Ip = 40 kA, Bj, = 2.1 T, PECRH = 130 kW]; (b) local parallel particle flux from Jsar profile<br />

in the scrape-off layer as a function of fluctuation driven cross-field flux 1 cm behind last closed flux<br />

surface in H2 discharges. [Ip = 40 kA, Bt = 1.1 T, PECRH = 155 kW]; (c) broadb<strong>and</strong> (40 to 250 kHz)<br />

root mean square poloidal field fluctuation level 1 cm behind the last closed flux surface as a function<br />

of edge density with conditions as for (a). For (a), (b) <strong>and</strong> (c), R = 1.19 m, a = 0.24 m.
