Radiological Risks of Neutron Interrogation of Food [PDF]

, 2015
In recent years there has been growing interest in the use of neutron scanning techniques for security. Neutron techniques with a range of energy spectra including thermal, white and fast neutrons have been shown to work in different scenarios.

Application of fluorine-based threshold activation detector for neutron flux calculation from D-T neutron generator [PDF]

EPJ Web of Conferences, 2020
In this paper we propose a method of fast neutron flux estimation from a pulsed D-T neutron generator with application of single CaF2 scintillation crystal.

Gravitoastronomy with neutron stars [PDF]

, 2004
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

Development of a dual-mode energy-resolved neutron imaging detector: High spatial resolution and large field of view

Nuclear Engineering and Technology
Energy-resolved neutron imaging is an effective way to investigate the internal structure and residual stress of materials. Different sample sizes have varying requirements for the detector's imaging field of view (FOV) and spatial resolution. Therefore,

Measurement of fluence at the D-line fast neutron facility at iThemba LABS [PDF]

, 2011
Measurements of fluence were made for the neutron beams produced at the fast neutron beam facility of iThemba LABS, using an NE213 organic liquid scintillator detector and a 238U fission ionisation chamber.

Development of cryogenic hydrogen gas target and estimation of background for a measurement of neutron inelastic scattering in 12C [PDF]

EPJ Web of Conferences
The triple-alpha reaction is a key process in nucleosynthesis, and its reaction rate can be enhanced by neutron induced deexcitation instead of by radiative decay.

The neutron production rate measurement of an indigenously developed compact D-D neutron generator [PDF]

Nuclear Technology and Radiation Protection, 2013
One electrostatic accelerator based compact neutron generator was developed. The deuterium ions generated by the ion source were accelerated by one accelerating gap after the extraction from the ion source and bombarded to a target.
