“…Measurement of neutron fluxes in these conditions can be successfully carried out using activation detectors. Activation detectors allow it possible to make measurements with a shift in time with respect to the moment of plasma generation after extinguishing of electromagnetic radiation and the cessation of interference [16][17][18][19]. Measurements produce on standard equipment and with greater accuracy than the accuracy achieved indirect measurements of the amplitude of the neutron pulse.…”

Present work presents calculations and experimental studies on the formation and dynamics of plasma on the "plasma focus" set up. Physical conditions were determined and critical parameters were calculated for estimating the neutron yield for kilojoule and megajoule set ups. The results of plasma diagnostics and flow formation in the CPA-30 and PF-4 set ups are also shown. A comparison of calculated data and experimental values is performed. The value of the neutron yield parameter is justified and the possible cause of the appearance of saturation is indicated. The rationale for the development of further research in the direction of creating conditions for thermonuclear fusion in installations of the plasma focus type is given. The neutron flux was observed on high-voltage gas discharges with a specific geometry of the electrodes. The result of measuring the anisotropy of the neutron yield along the axial z and radial φ directions was equal to Yn(z)/Yn(φ)~ 2 ÷ 3, which contradicts the thermonuclear mechanism.
