摘要:
The nonlocal power absorption of trapped ions in ion cyclotron radio‐frequency heating is calculated for several non‐Maxwellian distribution functions by keeping the full particle orbit and wave coupling. For slowing down distribution the finite Larmor radius effect enhances the power absorption in higher harmonic heating withn≥2. In bi‐Maxwellian plasma the absorption of trapped ions increases with the power of the ratio of the thermal perpendicular energy to the thermal parallel energy in the infinite aspect ratio limit and is slower in the small inverse aspect ratio case.
