Abstract

The developed spherical plasma focus model is used to investigate the neutron production and radiations emitted at the pinch. Theory of the neutron yield and radiations emitted in the radiative phase of the spherical plasma focus device is included in this paper. Since the neutron yield in the spherical plasma focus is from the beam-target neutron production mechanism, the beam-target neutron production is used for calculating the neutron yield. The achieved neutron yield with 14.5 Torr of DT mixture (1:1) filling gas, 25 kV of charging voltage and 432 muF of capacitor bank is 1.3 × 103. This result agrees to a large extend with other experimental measured value. The effect of the bremsstrahlung, radiative recombination and line radiations as the energy loss terms and of the Joule heating with the plasma resistance as the energy gain term on the plasma column is investigated. Plasma-ion density, beam-ion density and beam-ion speed are calculated under the diode voltage in the radiative phase of the spherical plasma focus.
