    The pinched plasma being in a stationary state has been discussed in the past by various investigators on the basis of the Vlasov equation. But the stationary or undisturbed distribution functions given by them are some-what scattered so that profiles of macroscopic quantities are also different. We shall here give a solution of a stationary pinched plasma apart from its stability using the. London equation with the equations of magnethydrostatic equilibrium. The reason that we shall apply the London equation to the collisionless plasma is due to the fact that the equation gives the total energy minimum with respect to the magnetic field on the basis of variational principle.

    Plasma production was studied using a 1 KW 130 MNz electromagnetic wave, a coupling coil placed in a metal vacuum-chamber, and a uniform magnetic field. Plasma densities higher than 1012 cm-3 were obtained in helium for gas pressures above about 10-3 torr. The ion-and electron-temperature reached 25 eV near the magnetic field strength satisfying the condition for the occurrence of lower hybrid resonance. There the efficiency for power transfer was estimated to be several tens of percent.

  • Parametric Excitations of Lower Hybrid and Cyclotron Sound Modes in a Plasma
    S. Takamura, T. Okuda
    1973 Volume 29 Issue 1 Pages 30-38

    Lower hybrid and cyclotron sound modes are excited parametrically by r. f. electric field. Anom lous absorption of extraordinary waves is tried to be explained by this parametric excitations.
    In a high frequency heating of a plasma the above effects are important in the case of the intense electromagnetic wave, while the linear transformation is the basic process in the case of weak intensity.
