The axial propagation of plasma in a current interrupter with radial injection guns has been experimentally studied. In the absence of a generator current passing through the injected plasma, the plasma front with a density of no less than 1011 cm-3 moves in the axial direction at a velocity of ∼(1-1.5) × 107 cm/s. At a distance of 20 cm from the injection plane, a plasma density of ∼1013 cm -3 is attained 5-6 μs after the current switch on in the guns; at a distance of 50 cm, the plasma density reaches ∼(2-5) × 10 12 cm-3.
