“…[3][4][5][6][7] This renewed interest is motivated, among others, by the technological perspective of using the PF as a compact, transportable, and intense source of pulsed fast neutrons. 8 The strategy included constructing low energy generators to produce high currents by using low inductance designing concepts and low capacitance capacitor banks. As a result of the inductance and capacitance reduction, the characteristic times for the evolution of the discharge have been decreased from microseconds up to hundreds or tens of nanosecond.…”

The purpose of this work is to discuss the techniques related to the detection of fast pulsed neutrons produced in plasma focus (PF) devices, the statistical analysis of the corresponding data, and the methodologies for evaluation of the device performance in low emission neutron sources. A general mathematical framework is presented for the assessment of the reproducibility of the neutron emission of small PF devices given the shot-to-shot distribution and detector efficiency. The effect on the reproducibility in case of using two independent detectors is also discussed. The analysis is applied to the neutron emission of the plasma focus device PF-50J operating in repetitive mode (0.1-0.5 Hz and 65 J bank energy). V C 2012 American Institute of Physics. [http://dx.
