Nanosecond neutron source of thermonuclear neutrons (Plasma-focus type) NSNS-2

Technical data:

Neutron energy: 2.45 MeV from the deuterium-deuterium reaction in plasma
Neutron burst I: duration: from 10 to 20 ns
repetition: ≥ 60 s
neutron yield during the burst ≥ 106 n/shot
Neutron burst II: duration: from 50 to 100 ns
repetition: ≥ 600 s
neutron yield during the burst ≥ 109 n/shot

Applications:

Pulsed nanosecond sources of thermonuclear neutrons are used for elaboration of methods of detection of neutron fields (space, energy and time distributions of neutron fluxes) mostly for the UE EURATOM programme and also for nuclear geophysics and nuclear medicine (radiation dosimetry). Nanosecond neutron pulses enable measurement of energy spectra of fast neutrons by the time-of- flight (TOF) method on a short base (a few meters). This will be helpful for development of new methods of measurements of neutron spectra at thermonuclear facilities (e.g. stellarator W-7X constructed in Greifswald, Germany) and neutron methods for detection of hidden illicit materials (e.g. explosives).
