Neutrons are sourced from the SAFARI-1 nuclear research reactor operated by Necsa. Necsa is located at Pelindaba in the Northwest Province of South Africa, which is 30 km west of Pretoria. The South African Neutron Radiography (SANRAD) facility is located on the beam port floor of the SAFARI-1 nuclear research reactor hall and sources neutrons from beam port No. 2. The facility has neighbouring...

A new pulsed-neutron instrument, named the Energy-Resolved Neutron Imaging System “RADEN”, has been constructed at the beam line of BL22 in the Materials and Life Science Experimental Facility (MLF) of J-PARC. The primary purpose of this instrument is to perform energy-resolved neutron imaging experiments through the effective utilization of the pulsed nature of the neutron beam, making this th...

There is a growing need to rapidly scan bulk air cargo for contraband such as illicit drugs and explosives. Ideally, cargo containers must be imaged without unpacking and with scan times of less than one minute. Fast neutron techniques are particularly attractive for screening cargo as they can be used to determine cargo composition. The Commonwealth Science and Industrial Research Organisation...

Freezing of fluids in capillary structures affects systems that range from soils to the polymer membranes that are used in fuel cells. Neutron radiography can be used to image phase change within otherwise opaque structures and previous studies have shown the capability of quantitative imaging of freezing at 3 mm scale. In this study, a 1.6 mm diameter water column within an aluminum rod was im...

Until recently fabrication techniques of Renaissance bronzes have been studied only with the naked eye, microscopically, videoscopically and with X-radiography. These techniques provide information on production techniques, yet much important detail remains unclear. As part of an interdisciplinary study of Renaissance bronzes undertaken by the Rijksmuseum Amsterdam, neutron-imaging techniques h...

Neutron radiography was researched to detect the linear density of explosive in linear shaped charge (LSC), to determine its distribution uniformity and defective. The clear images of some samples were obtained by neutron radiography, and were processed to obtain the linear density of inner explosive. The defectives such as sparseness, discontinuity and cavity were shown clearly in the images. ...

A power cable is the most important part in a power transmission system. The cables must be total quality dedicated and certified for development, manufacturing and installation, however are exposed to a corrosive environment. The purpose of this paper is to show that the fast neutron radiography with a transportable system is a solution to find defects in the cables and reduce the cost of insp...

Applications of NR in archaeology are indicated when searching for the presence of materials containg hydrogen like organic materials wood, fabrics, leather, or corrosion products and by metals, in particular heavy metal lead. In the recent years the thermal neutron radiography (NR) has become a common non-destructive examination method at the National Museum of Slovenia, usefully complementing...
