The cathode plasma jet deceleration caused by interaction with a secondary ion cushion at the anode is analyzed. The secondary ions are assumed to be sputtered or/and reflected from the copper anode. It was found that for an inter-electrode gap of L = 2 cm, and a secondary ion velocity of 103m/s, there is no upper limit for the current density for continuous jet motion. For a secondary ion velocities <0.25×103 m/s the upper limit is 105 A/m2.
