Theoretical Interpretation of Alfv en Cascades in Tokamaks with Non-monotonic q-pro les
نویسندگان
چکیده
Alfv en spectra in a reversed-shear tokamak plasma with a population of energetic ions exhibit a quasiperiodic pattern of primarily upward frequency sweeping (Alfv en Cascade). Presented here is an explanation for such asymmetric sweeping behavior which involves nding a new energetic particle mode localized around the point of zero magnetic shear.

متن کاملPreprint: Alfv¶en Wave Instability of Current Sheets in Force-Free Collisionless Plasmas
If the current sheet between adjacent twisted magnetic °ux tubes is suf̄ciently thin, the electron °ow velocity becomes comparable to the Alfv¶en velocity and can destabilize collisionless Alfv¶en waves. The threshold for instability in force-free plasmas is calculated for both inertial and kinetic Alfv¶en wave regimes. When there is strong magnetic shear, unstable kinetic Alfv¶en waves can reso...
متن کاملTemporal Evolution of Drift Alfv en Waves in an Inhomogeneous Plasma with Homogeneous Shear Flow
The temporal evolution of drift-Alfv en waves in a plasma ow with homogeneous shear is studied as an initial value problem without the use of spectral expansion in time. It is shown that the conventional modal structure of the drift-Alfv en instability (as well as drift and Alfv en waves) pertains only in the initial stage of its evolution. For larger times, non-modal e ects due to the velocity...
متن کاملLinear theory and measurements of electron oscillations in an inertial Alfv en wave
The physics of the aurora is one of the foremost unsolved problems of space physics. The mechanisms responsible for accelerating electrons that precipitate onto the ionosphere are not fully understood. For more than three decades, particle interactions with inertial Alfv en waves have been proposed as a possible means for accelerating electrons and generating auroras. Inertial Alfv en waves hav...
متن کاملNon-linear Alfv en wave interaction leading to resonant excitation of an acoustic mode in the laboratory
The nonlinear three-wave interaction process at the heart of the parametric decay process is studied by launching counter-propagating Alfv en waves from antennas placed at either end of the Large Plasma Device [W. Gekelman et al., Rev. Sci. Instrum. 62, 2875 (1991)]. A resonance in the beat wave response produced by the two launched Alfv en waves is observed and is identified as a damped ion ac...
