Study of HF plasma turbulence excited by REB

The results of investigation of HF turbulent plasma oscillations, excited by a powerful relativistic electron beam in the plasma column placed in a longitudinal magnetic field are presented. The observation of the pulsed CO

rad is the main diagnostic method. A five-channel system of the scattered radiation recording provides information on the frequency and wave number spectrum of the turbulence during a pulse. Two additional diagnostic methods are used. The first one is a studying of hydrogen lines Stark profiles. The second one is an observation of plasma frequency harmonics in a submillimeter spectral range.
