SCREW AND FLUTE INSTABILITIES IN A LOW-PRESSURE PLASMA (in Russian)
Under certain conditions, plasma may be contained by a transversal magnetic field. If the plasma pressure is low with respect to the energy density of the magnetic field, the field is the same in the presence of plasma and in vacuum. A transversal motion of the plasma is theoretically impossible but other types of motion, not accompanied by a change of the magnetic field, may ultimately result in the escape of the plasma. Such cases, involving flute and screw instabilities were more closely examined; mechanisms involved in the formation of spatial charges, such as the gravitation-induced drift, centrifugal forces, inertia forces generated by magnetic pinch, and the effect of the Larmor radius. The results of the calculations indicated a strong interaction between the mechanisms corresponding to the flute and screw instabilities; these mechanisms are able to create instabilities in both partially and completely ionized gases. The theory developed is based on the equations of the macroscopic motion of the gas, as defined by the Boltzmann equation. (TTT)
