Anisotropic Electron Tail Generation during Tearing Mode Magnetic Reconnection.
The first experimental evidence of anisotropic electron energization during magnetic reconnection that favors a direction perpendicular to the guide magnetic field in a toroidal, magnetically confined plasma is reported in this Letter. Magnetic reconnection plays an important role in particle heating, energization, and transport in space and laboratory plasmas. In toroidal devices like the Madi...
متن کاملAnisotropic ion heating and tail generation during tearing mode magnetic reconnection in a high-temperature plasma.
Complementary measurements of ion energy distributions in a magnetically confined high-temperature plasma show that magnetic reconnection results in both anisotropic ion heating and the generation of suprathermal ions. The anisotropy, observed in the C(+6) impurity ions, is such that the temperature perpendicular to the magnetic field is larger than the temperature parallel to the magnetic fiel...
متن کاملFast and Slow Nonlinear Tearing Mode Reconnection
1. Introduction. The standard theory of the tearing-mode evolution identifies three stages. The first is the linear stage described by the Furth–Killeen–Rosenbluth (FKR) theory [1]. During this stage, the island width W grows exponentially in time until it reaches the width of the resistive dissipation layer, ℓ η ∝ η 2/5 ∆ ′1/5 , where η is the resistivity and ∆ ′ is the instability parameter [...
متن کاملMagnetic Reconnection in High - Temperature Plasmas : Excitation of the Drift - Tearing Mode and the Transport of Electron Thermal Energy
The problem of excitation of the drift-tearing mode (Coppi, 1964) in high-temperature plasmas is considered. Existing theories predict that under the conditions typical of modern toroidal experiments on nuclear fusion, the mode is linearly stable in both collisionless (Coppi et al., 1979), and in a weakly collisional (Antonsen and Drake, 1983) regimes. We propose that the presence of a spectrum...
