Effect of resonance broadening on the evolution of the edge of a turbulent spectrum
The extent to which nonlinear wave-particle resonance broadening results in a narrowing of an incident lower-hybrid wave spectrum is investigated. This narrowing is of concern because it could make control of lower-hybrid heating difficult. We numerically show, however, that relatively uniform spatial power deposition occurs if resonance broadening effects are treated consistently on both the wave spectrum and the particle distribution. A more naive approach, including only the effects on the evolution of the wave spectrum, would incorrectly predict an unfavorable power deposition profile.
