Abstract :
In the plasma focus discharge with the total neutron yield 1010 – 1011 about 70% of neutrons was generated by deuterons moving with the dominant velocity component in the downstream direction. About 10% of fast deuterons moved with dominant velocity component in the direction upstream and minimally 20% had the dominant side-on velocity component. We evaluated energy distribution of deuterons producing neutrons and we discussed a possibility of neutron production from the dense and hot structure, which forms at the beginning of the stagnation phase and transforms to the sphere at the heel of the umbrella-shape current sheath and finally we discussed the possibility of heating of this dense structure by the fast deuterons.
