The statistical properties of the plasma fluctuations in a long plasma column produced by a hollow cathode arc discharge show that different states of weak plasma turbulence exist. The transition between these states occurs as a result of changes in the confining magnetic field, the background gas pressure, and the boundary conditions. Associated with such transitions are radical changes in the plasma confinement. A sudden jump in the radial particle loss rates is manifested by the increase of the current collected by Buchelnikova ring‐collectors and by the change in the radial density profiles measured by electrostatic probes.
