NOTES ON PLASMA OSCILLATIONS,

Abstract

The full spectrum of oscillations generated in a low-pressure, low-voltage hot-cathode plasma maintained by an electron beam is outlined. It has been confirmed that a number of frequencies occur in the plasma-electron band but the simultaneity of the oscillations in a sufficiently short time scale is questioned. Problems also arise in connection with the reality and amplitude of harmonics and subharmonics. Study of ion-band oscillations showed the need for simplification of plasma geometry. A cylindircal tube constructed with this aim has proved to be a source of intermediate band (30 - 200 Mc/s) oscillations, which are being actively investigated. Some new experiments are also being done on two-beam instability, and on plasma-electron concentration contours. (Author)
