Plasma flow in the reversed field pinch STP-3(M)

In the reversed field pinch STP-3(M), plasma flow propagating in the direction of the electron movement along the magnetic field lines of force is found by measurements of magnetic fluctuations and Doppler shift of impurity lines. The magnitude of the flow velocity is smaller than the thermal speed of the plasma ions by about a factor of three. Thus, it is demonstrated experimentally that the theoretical assumption of no mass flow in a reversed field pinch is justified.
