A planar e-beam diode with a strong magnetic field imposed normal to the electrode surfaces, has been found to operate as a fast opening switch when the electric field of the cathode was artificially enhanced with an array of needles as the emitting structure. Conduction times of hundreds on nanoseconds and voltages of order 400 kV are routinely achieved with this switch. Data from experiments using two different pulsed power drivers are presented along with a simple 1-D model to provide one possible mechanism to explain this observed behavior.
