Neutrons

Neutron Science Facility (NSF)

The establishment of a Neutron Science Facility (NSF) is a priority for years 2019-2021. It includes the implementation of two neutron generators, their safety components as well as the ancillary experiments. The facility will expand NSIL capabilities to assist MSs utilizing and developing the peaceful use of nuclear techniques and related applications based on neutrons

The NSF will be based on the utilization of two compact neutron generators, i.e. electrically controlled neutron sources of limited intensity (up to 4•108 n/s over 4π) and whose neutron emission is stopped when the system is switched off. Thus, neutron generators are an attractive alternative to isotopic neutron sources, which exhibits continuous neutron and gamma emission, or to nuclear research reactors, which are much more costly, complex and infrastructure-extensive facilities.

Modern neutron generators integrate in a sealed tube a very compact linear accelerator that produces neutrons by the fusion of two isotopes of hydrogen: Deuterium-Deuterium (DD) to produce 2.45 MeV neutrons (energy equivalent to the mean energy of fission neutrons) or Deuterium-Tritium (DT) to produce 14.0 MeV neutrons (fusion neutrons as in a fusion DT-based Tokamak). The NSF will be equipped with both types of generators, one DD and one DT generator, the former one being easily transportable to MSs to provide in-situ training and possible services.

The NSF will be used for

·         capacity building through education and training,

·         facilitation of applied research, and

·         provision of specialized services.

Some examples of DD- and DT-based neutron sources are illustrated below
