Plasma Instabilities

Drift instability arises due to the pressure gradient in a plasma, leading to the formation of density fluctuations and transport.

Kink instability is driven by the current density gradient in a plasma, causing the plasma column to bend and potentially disrupt.

Ballooning instability is driven by the pressure gradient and magnetic field curvature in a plasma, leading to the formation of elongated structures called 'balloons'.

Tearing mode instability is driven by the current density gradient and magnetic field curvature in a plasma, leading to the formation of magnetic islands.

Magnetic shear, which is the variation of the magnetic field direction across a plasma, is the primary mechanism for stabilizing drift instabilities.

Kinetic ballooning mode is driven by the interaction between energetic particles and waves in a plasma, leading to the formation of large-scale instabilities.

Resistive tearing mode instability is driven by the resistivity of the plasma, which allows magnetic field lines to reconnect and form magnetic islands.

Zonal flow instability is driven by the interaction between turbulence and zonal flows, leading to the formation of large-scale, rotating structures.

Magnetic shear, which is the variation of the magnetic field direction across a plasma, is the primary mechanism for stabilizing kink instabilities.

Neoclassical tearing mode instability is driven by the interaction between a plasma and an external magnetic field, leading to the formation of magnetic islands.

Trapped particle mode instability is driven by the interaction between trapped particles and waves in a plasma, leading to the formation of instabilities.

Blob formation instability is driven by the interaction between turbulence and density gradients, leading to the formation of small-scale, localized structures called 'blobs'.

Magnetic shear, which is the variation of the magnetic field direction across a plasma, is the primary mechanism for stabilizing ballooning instabilities.

Neutral beam injection driven instability is driven by the interaction between a plasma and a neutral gas, leading to the formation of instabilities.

Ion temperature gradient mode instability is driven by the ion temperature gradient in a plasma, leading to the formation of instabilities.
