By an annular magnetically insulated ion diode operated in long pulse mode, total ion current of 5 kA and ion current density over 30 times the Child-Langmuir limit are achieved. Average length of electron drift by E×B force in the gap is measured to be about three times the gap length. Based on fundamental theory, the ion production efficiency is estimated by this length consistent with the experimental value (20%). The value of E × B current evaluated from this length is enough to change the applied magnetic field. It is predicted by the theory describing ion flow enhancement.
