Full wave simulations of lower hybrid wave propagation in tokamaks
Lower hybrid (LH) waves have the attractive property of damping strongly via electron Landau resonance on relatively fast tail electrons at (2.5−−3)× vte, where vte ≡ (2Te/me) is the electron thermal speed. Consequently these waves are well-suited to driving current in the plasma periphery where the electron temperature is lower, making LH current drive (LHCD) a promising technique for off-axis...
متن کاملLower-Hybrid-Drift Wave Turbulence in the Distant Magnetotail
Recent satellite observations of electrostatic and magnetic noise in the distant magnetotail (Gurnett et al., 1976) can be explained by the excitation of the lower-hybrid-drift instability. In particular, it is shown that (1) existence conditions for the lower-hybrid-drift instability can be met, (2) the observed frequency spectra and polarization are in good agreement with the predictions of l...
متن کاملStochastic Ion Heating by a Lower Hybrid Wave: II
∣ ≪ |k⊥| and ω ≫ Ωi) in a tokamak plasma is studied. For ions satisfying v⊥ > ω/k⊥, the Lorentz force law for the ions is reduced to a set of difference equations which give the Larmor radius and phase of an ion on one cyclotron orbit in terms of these quantities a cyclotron period earlier. From these difference equations an earlier result [Phys. Fluids 21, 1584 (1978)] that above a certain wav...
متن کاملLetters Lower Hybrid Wave Excitation by a Fast Wave Current Drive Antenna
Excitation of the lower hybrid wave (slow wave) using a launcher designed for fast wave excitation has been observed under conditions where neither direct excitation nor mode conversion is expected to take place. The slow wave was revealed through the presence of its resonance cone. The experiment was performed with £2j < to <€ J2e. The coupling of the fast wave into the slow wave is attributed...
متن کاملCoupling of M–branes in M–theory
Coupling of a membrane and a five-brane to the bosonic sector of D = 11 supergravity is considered. The five–brane is a dyonic object which carries both an electric and a magnetic charge of the D = 11 three-form gauge field A, and it couples not only to A but also minimally couples to a six-form field A dual to A. This implies that the 5-brane should more naturally couple to a version of D = 11...
