Investigations are described on the spontaneous oscillation of plasmas maintained by low-voltage electron beams in gas at a pressure of about 0.001 mm Hg. Previous work on oscillations in the plasma electron band frequency of order of hundreds of Mcs and the plasma ion band frequencies below a few Mcs is supplemented by observations on surface waves with frequencies in a broad intermediate band. The bearing of the electron-ion oscillation interaction on plasma turbulence is discussed. The interaction may permit of transfer of electron beam energy to thermal energy of the ions and gas.
