Abstract: The development of a portable plasma accelerator unit, the smallest plasma focus device that can be operated to produce pulsed neutrons in 10 Hz repetition rate, has been reported in the present paper. The unit consists of coaxial stainless electrodes with an alumina insulator sleeve. The inner diameter and the effective length of the unit are 4 cm and 12 cm, respectively. The device is operated at 500 J (10 µF, 10 kV). An open air triggered spark gap switch is used. The repetitive operation is achieved by sequentially synchronizing charging pulse and triggering pulse. For a single shot operation, the average yield was (1.3±0.2)105 neutrons per shot. For 10 Hz operation, the average yield was (1.4±0.3)106 neutrons/s.
