FIG. 1.

Schematic cross section of the plasma focus PF-1000 vessel.

FIG. 2.

Position of monitors M1, M2, and Bonner spheres around the plasma focus device. Four silver activation detectors are hanging from the ceiling.

Image of FIG. 3.
FIG. 3.

Neutron spectra (group representation) behind a circular slab of different thickness made from the same material as the walls of the plasma focus vessel (irradiated by 2.45 MeV neutrons, calculated using the MCNP code).

Image of FIG. 4.
FIG. 4.

Relative TLD responses to neutrons in the Bonner spheres measured outside of the plasma focus vessel.

Image of FIG. 5.
FIG. 5.

Neutron spectra (group representation) measured by the plasma focus device and normalized to monitor M1 response. Spectra calculated by the MCNP code, which were used as a priori spectra, are not normalized as the measured ones; they are shown only for comparison of spectral shapes.

Neutron yield measured by M1 and M2 monitors and by BSS normalized to 1 nC of M1 monitor.
