Damping of the trapped-particle diocotron mode.
The damping mechanism of a recently discovered trapped-particle mode is identified as collisional velocity scattering of marginally trapped particles. The mode exists on non-neutral plasma columns that are partially divided by an electrostatic potential. This damping mechanism is similar to that responsible for damping of the dissipative trapped-ion mode. The damping rate is calculated using a ...
متن کاملDiocotron and Kelvin mode damping from a flux through the critical layer.
Experiments and theory characterize a novel type of spatial Landau damping, caused by a flux of particles through the wave or rotation resonance (critical) layer. Pure electron plasma experiments demonstrate that a steady flux of particles causes algebraic damping of diocotron mode amplitudes for azimuthal modes m = 1 and m = 2, and a simple model of dynamics in the nonlinear cat's eye clarifie...
متن کاملSubharmonic autoresonance of the diocotron mode*
This paper investigates the excitation and control of the driven l51 diocotron mode in a pure electron plasma by adiabatic passage through higher order resonances. The excitation takes place when the driving frequency vd is swept such that its n th harmonic passes through the linear diocotron mode frequency v0 ; vd'v0 /n , n52,3, . . . . Once past the resonant region, the mode enters the autore...
متن کاملCollisional damping of ETG-mode-driven zonal flows.
We study collisional damping of electron zonal flows in toroidal electron temperature gradient (ETG) turbulence due to the friction between trapped and untrapped electrons. With the assumption of adiabatic ions, the collisional damping is shown to occur on fast time scales approximately 0.24epsilon(1/2)tau(e). The comparison with the growth rate of electron zonal flows indicates that the sheari...
متن کاملSimulations of the instability of the m=1 self-shielding diocotron mode in finite-length non-neutral plasmas
The "self-shielding" m = 1 diocotron mode in Malmberg-Penning traps has been known for over a decade to be unstable for finite length nonneutral plasmas with hollow density profiles. Early theoretical efforts were unsuccessful in accounting for the exponential growth and/or die magnitude of the growth rate. Recent theoretical work has sought to resolve the discrepancy either as a consequence of...
