Ion hose instability

WebThe growth and saturation of the ion-hose instability in an applied axial magnetic field is examined. This dipole streaming instability is an important factor in determining the time … WebA Plasma instability is a region where turbulence occurs due to changes in the characteristics of a plasma (eg. temperature, density, electric fields, magneti fields). As the name suggests, instabilities are unstable, though they may appear to evolve through different forms (morphology).
