The PF-1000 plasma focus was modified by adding the cathode disk 3 cm in front of anode. This modification facilitated evaluation neutron energy spectra. Two pulses were distinguishable. As regards first pulse, it lasted 40 ns during stagnation and demonstrated high isotropy emission. A peak detected upstream 2.46±0.02 MeV. full width spectra 90±20 keV enabled to calculate an ion temperature 1.2 keV. These parameters a yield 109 corresponded theoretical predictions for thermonuclear neutrons.
