“…Being warned that an accurate collimator could reduce the neutron flux from 5 × 10 8 n cm −2 s −1 to 4×10 4 n cm −2 s −1 [12], and constrained by our very limited neutron flux, there is a need to simplify the typical collimator design shown in figure 11 by reducing some of its relatively uncritical or even irrelevant components in our case.…”

The Nuclear Science and Instrumentation Laboratory (NSIL) is currently establishing a Neutron Science Facility (NSF) based on two compact neutron generators: Deuterium-Deuterium (DD), resulting in 2.45 MeV neutrons, and Deuterium-Tritium (DT), resulting in 14.1 MeV neutrons, with maximum source intensities up to 5 × 106 n/s and 4 × 108 n/s over 4π, respectively. Neutron/X-ray radiography and tomography are two of the applications the NSF will be equipped with. In this paper, we report the state of the radiography and tomography system, and the neutron/X-ray radiography and tomography experiments we performed. Good radiographs and tomographs are obtained with X-ray. The spatial resolution of the X-ray radiography system is measured to be about 0.1 mm. The thermal neutron radiographs and fast neutron radiographs have proved that the DD neutron generator will be beneficial to demonstrate neutron radiography capabilities for educational purposes. Additionally, the detail of the collimator optimization of the DD neutron radiography was presented.

“…The neutron scattering technique has the potential to be used in the industry as one of the methods for identifying sludge in tanks. Neutron particles have characteristics to interact with hydrogen atoms contained in crude oil [ 7 ]. Research in Malaysia stated the success of water measurement in paper recycling industry using neutron backscatter technique [ 8 ].…”
