Electromagnetic Wall Torques from Magnetically Confined Plasmas
A direct method to measure the localized magnetic shear stress and hence electromagnetic torque or force exerted on a wall by a fluctuating magnetic field is presented. A model of the wall is needed when the magnetic measurements do not include the normal component. Explicit formulas for thin and thick walls are given. Estimates of the force in illustrative Alcator C-Mod tokamak plasmas provide...
متن کاملRunaway expansion in magnetically confined electron plasmas
Magnetic confinement of neutral plasmas in a tokamak is one of the most promising avenues for generating power via nuclear fusion. Plasma disruption and energy loss, however, continue to cause problems even as larger experimental plants are being built. In particular, cyclical disruption of the plasma’s core electron temperature is a persistent but poorly explained phenomenon. In this paper, I ...
متن کاملSpectral Signatures of Gravitationally Confined Thermonuclear Supernova Explosions
We consider some of the spectral and polarimetric signatures of the gravitational confined detonation scenario for Type Ia supernova explosions. In this model, material produced by an off-center deflagration (which itself fails to produce the explosion) forms a metal-rich atmosphere above the white dwarf surface. Using hydrodynamical simulations, we show that this atmosphere is compressed and a...
متن کاملMicrostability of magnetically confined electron-positron plasmas.
It is shown that magnetically confined electron-positron plasmas can enjoy remarkable stability properties. Many of the microinstabilities driving turbulence and transport in electron-ion plasmas are absent if the density is so low that the Debye length is significantly larger than the gyroradius. In some magnetic configurations, almost complete linear stability may be attainable in large parts...
متن کاملNonlinear Effects in Strong Turbulence in Magnetically Confined Plasmas
Strong electrostatic turbulence in magnetically confined plasmas is characterized by trapping or eddying of test particle trajectories produced by the E B stochastic drift. Trapping is shown to produce non-standard statistics of trajectories: non-Gaussian distribution, memory effects and quasi-coherence. Two types of effects produced by trapping are analyzed. The first type concerns particle an...
