Theory of synergy between electron cyclotron and lower hybrid waves

Saturation of electron cyclotron maser by lower-hybrid waves

We perform a numerical study on the quasilinear relaxation of an electron cyclotron maser on the initially dominant mode. We focus thereby on a situation where the initially dominant modes are quasi-electrostatic lower hybrid (lh) waves, which have not been treated in preceding studies. To this end, we chose 0.2 ≤ ωp/ωBe < 0.5 (ωp: plasma-, ωBe: electron cyclotron frequency) and an initial loss...

Ultrahigh resolution simulations of mode converted ion cyclotron waves and lower hybrid waves

Full Wave studies of mode conversion (MC) processes in toroidal plasmas have required prohibitive amount of computer resources in the past because of the disparate spatial scales involved. The TORIC code [1] solves the linear sixth order reduced wave equation for the ion cyclotron range of frequencies (ICRF), in toroidal geometry using a Fourier representation for the poloidal dimension and fin...

ITER Relevant Simulations of Lower Hybrid and Ion Cyclotron Waves with Self-Consistent Non-Maxwellian Species

The next step toward fusion as a practical energy source is the design and construction of ITER. ITER relies in part on ion-cyclotron radio frequency (ICRF) power to heat the deuterium-tritium plasma to fusion temperatures as well as to provide a portion of the current during flat-top operations. Lower hybrid (LH) RF power is under consideration as an upgrade to the baseline heating and current...
