Abstract

A methodology is elaborated and applied to taxonomy of large chambers of thermonuclear fusion reactors. It ensures a feasibility to describe impairments produced by environment and details of the chamber into the neutron field generated during the operation of a reactor. The method is based on application of very bright nanosecond neutron flashes irradiated from a compact neutron source of a dense plasma focus type. A number of neutron activation procedures as well as a neutron time-of-flight method were applied to trace deviations of neutron 3-D fields after their interaction with the simulator of the above chamber. Monte-Carlo modeling of these processes gained the data on the most important elements that influenced on the fields.

Keywords: nuclear fusion reactors, dense plasma focus, nanosecond neutron pulses, neutron activation diagnostics, time-of-flight spectral diagnostic
