通过在WT-2环形装置的电子回旋共振处向微波放电等离子体中注入低杂波，产生环形等离子体电流，启动电流高达I/sub p/approx。=5 kA，并且仅由射频功率维持，而没有欧姆加热功率（rf托卡马克）。这种低混合波驱动电流仅在高能量尾电子与低混合波共振相互作用时产生，该尾电子存在于初始电子回旋共振等离子体中。
By injecting the lower hybrid wave into the microwave discharge plasma at the electron-cyclotron resonance in the WT-2 toroidal device, the toroidal plasma current is generated, started up to I/sub p/approx. =5 kA, and sustained by rf power alone, without the ohmic heating power (rf tokamak). This lower-hybrid-wave--driven current is produced only when high-energy tail electrons, which interact resonantly with the lower hybrid wave, are present in the initial electron-cyclotron resonance plasma.
