Neutrons

Neutron Science Facility (NSF)

The recent establishment of a Neutron Science Facility (NSF) included the installation and commisioning of two neutron generators, their safety components as well as the ancillary experiments. The facility expands NSIL capabilities to assist MSs utilizing and developing the peaceful use of nuclear techniques and related applications based on neutrons

The NSF includes 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 is equipped with both types of generators, one DD and one DT generator, the latter being easily transportable to MSs to provide in-situ training and possible services.

The NSF is currently used for:

·         capacity building through education and training (see available experiments​),

·         facilitation of applied research, and​

·         provision of specialized services.

Some examples of DD- and DT-based applications are illustrated below
