Ion saturation current and floating potential fluctuations are recorded by movable array of 4 Langmuir probes near
the boundary of the confinement region in the l = 3/m = 9 Uragan-3M torsatron with an RF produced and heated
plasma. On the basis of these data main spectral and time characteristics of the low frequency electrostatic turbulence
have been derived. The existence of the radial electric field shear and reversal of poloidal phase velocity of the
fluctuations at the plasma boundary have been confirmed. The time function of the turbulent E×B particle flux contains
intermittent bursts with the amplitude multiply exceeding the average flux. Up to 70% of the total fluctuating flux is
carried in these bursts.
