RADIAL OSCILLATIONS AND STABILITY OF A CYLINDRICAL PLASMA (in French)

Journal Article · · Bull. classe sci., Acad. roy. Belg.
OSTI ID:4159202
A homogeneous, cylindrical, completely ionized plasma in equilibrium under the effect of its own gravity and in the presence of a longitudinal uniform magnetic field Bp is considered. The vacuum surrounding the plasma is supposed to be pervaded by a longitudinal uniform magnetic fleld Bv and by a toroi-dal magnetlc field caused by a sheei current flowing on the surface of the plasma. With the classical hypothesis of magnetohydrodynamics -scalar pressure, infinite electrical conductivity, and adiabatic changes-the dynamic stability of this equilibrium with respect to irfinitely small radial perturbations is discussed Application to the so-called pinch effect is obtained by neglecting gravitation in the general results.
