The interaction of pulsed high-current beams with a plasma in a magnetic field

A study was made of the interaction of electron beams of currents up to 8.5 A and energies up to 15 keV with a plasma in a magnetic field the strength of which varied within the limits of 360-1320 oersted. The energy distribution of the electrons after the beam had passed through the plasma was investigated as a function of the beam current, the residual gas (air) pressure and the strength of the longitudinal magnetic field. The intensities of the transverse and longitudinal high-frequency fields established by the beam in the plasma were measured; they attained values of the order of 100 V/cm and 1-2 kV/cm respectively. This is an indication that great energy losses by a beam, arising on its passing through a plasma, are due to the excitation of high-frequency oscillations.
