Steady-State Currents Driven by Collisionally Damped Lower-Hybrid Waves

Low-power (<50 W) lower-hybrid waves excited in a linear plasma were observed to drive electron currents (a few milliamperes per watt) in the direction of the wave momentum when the waves were collisionally damped. An approximate solution of an electron kinetic equation with a Lorentz collision operator predicts an electron current in this experimental regime ($\frac{k_{\parallel }{v}_t}{\omega }\sim \frac{\nu }{\omega }\ll 1$).
