Simulations confirm the Hull cutoff as the limiting stable current for a space charge limited planar crossed-field diode, proposed by Lau. In addition, a current occurs beyond the Hull cutoff, with a near-zero average value plus a high frequency oscillatory component which dies rapidly in time. The diode reacts strongly to small increases in injection current above the current limit and magnetic field above the Hull cutoff, with a rapid reduction of transmitted current. The simulations are performed in 1D3V, using PDP1.
