Summary:This paper presents the study of emission of the X-rays, fast electrons and neutrons from the plasma focus at the implosion of the deuterium plasma sheath. The discharges were carried out at the PF-1000 facility with the current amplitude of 2 MA. A good correlation of soft- and hard-X-rays and upstream electrons was confirmed. A distinctive anisotropy of upstream and side-on electrons with energy above 60 e V was observed. The mean energy of upstream neutrons was estimated as 2.7 MeV and of side-on neutrons as 2.5 MeV by pick to pick method. This value of energy enabled an estimation of ~50 ns time delay of maximum of neutrons after hard X-rays. Neutrons were produced at the time of plasma focus disintegration with ~50 ns FWHM as the FWHM of hard X-rays.
