“…Fig. 3 shows the power flux handling capabilities for various machines like Versator-II [7], JFT-2 [8], PLT [9], WT-2 [10], JT-60U [11], TRIAM-1M [12], JET [13], Tore Supra [14,15], Asdex [16], Alcator-C [17] and FTU [18] and its dependence on frequency and the width of the grill channel. The magnetic field for the machines is also shown in brackets in the same figure to show the growing trend with operating frequency and magnetic field.…”
