Tearing mode

Last updated

In plasma physics, a tearing mode is a plasma instability characterized by field line reconnection and the formation of magnetic islands. [1] [2] With islands emerging in the plasma, particles and heat can move from regions that were originally disconnected. Pressure and current density profiles are flattened, causing disruptions. [3] The typical timescale for the growth of a tearing mode the order of 10−1 microsec. [4] [5] [6]
