Abstract
Analysis of neutron fields around large chambers of main-stream nuclear fusion facilities is an important problem. The neutron emission from Dense Plasma Focus (DPF) device is anisotropic itself. It may be additionally distorted by an architecture details of the hall and construction elements of a facility hosting the particular DPF setup. The compact plasma focus device PF-6 is a quasi-point source producing nanosecond pulse of about 108 2.5-MeV neutrons with narrow energy spectrum. It was used for examination of a chamber of the large plasma installation PF-1000. The construction of the PF-1000 chamber simulates neutron scattering and absorption taking place in a main-stream fusion facility. The silver-based activation monitors were used for a survey of the neutron emission field in all directions. Such a device can be further used for inertial confinement fusion (ICF) and tokamak chambers examination and for calibration of its neutron diagnostics.
