Abstract

Abstract

A dense plasma focus (DPF) device with a Mather chamber was developed. The working principle and system composition of the DPF device are introduced, and the design of the DPF chamber is discussed in detail. The following technical parameters of the device were achieved: average neutron yield greater than 5.0×10⁸ /pulse(D-D) with neutron pulse width(FWHM) (40±5) ns when the charging voltage of the primary capacitors is greater than 19 kV and the deuterium gas pressure is 550-600 Pa. The device can be used for calibration of detector sensitivity in neutron and gamma radiation diagnostics, as well as to carry out researches on fast neutron radiography, neutron activation analysis and single event effect.
