متن کاملIdeal kink instabilities in line-tied coronal loops
We investigate the nonlinear development of ideal kink instabilities in a line-tied coronal loop, using a three dimensional numerical code. In order to understand how the equilibrium loop properties affect nonlinear evolution, various different initial magnetic equilibria are considered. In most cases, a finescale magnetic field structure is shown to develop. However, the corresponding electric...
متن کاملInstability, turbulence, and 3D magnetic reconnection in a line-tied, zero net current screw pinch.
This Letter reports the first experimental investigation into a line-tied plasma with a reversed current profile. Discrete current sources create a cylindrical plasma equilibrium with an axial field and zero net current. Detailed magnetic measurements show that an internal m=1 mode with no external character grows exponentially. The nonlinear evolution of the mode drives 3D reconnection events ...
متن کاملObservation of resistive and ferritic wall modes in a line-tied pinch.
The resistive wall mode is experimentally identified and characterized in a line-tied, cylindrical screw pinch when the edge safety factor is less than a critical value. Different wall materials have been used to change the wall time and show that the growth rates for the RWM scale with wall time and safety factor as expected by theory. The addition of a ferritic wall material outside the condu...
متن کاملThe form of ideal current layers and kink instability in line-tied coronal loops
We have investigated the characteristics of the current concentration which develops when an unstable line-tied coronal loop is driven by an ideal kink instability towards a secondary bifurcated magnetohydrodynamic (MHD) equilibrium. Using fully three dimensional MHD simulations in cylindrical geometry, the main results indicate an algebraic linear-like dependence of the thickness and amplitude...
