Electron extraction from a hollow cathode plasma discharge through a primary anode, biased with a DC accelerating potential, is controlled to produce either a pulsed or a continuous electron beam without interruption of the discharge. The beam is on while a secondary anode, interior to the hollow cathode, is electrically isolated. While the primary and secondary anodes are electrically connected, the beam is off. Pulses as short as 10 μs have been produced, rise times are
