Abstract
Experiments on fast plasma heating by the relativistic electron beam in the GOL-3 facility succeeds in the creation of a 10(15) cm(-3) plasma with ele ctron temperature of up to a few keV. The heating is produced due to two-st ream instability of the beam that causes high level of plasma microturbulen ce. The experiments show some specific features of plasma behaviour during the beam injection. The beam-induced turbulence is the reason of non-classi cal transport processes in the plasma. Anomalies in longitudinal thermal co nductivity, resistivity of the plasma and in lifetime of hot electrons are observed. Transition to classical transport coefficients occurs when the pl asma turbulence disappears after the beam injection stops.
