The replacement of radioactive sources with alternative technologies has been identified as a priority by international authorities, due to the risk of accidents and diversion by terrorists for use in Radiological Dispersal Devices. Many of these sources can be replaced with the X-rays produced by electron beams accelerated to MeV energies. However, the size, weight, and costs of electron...
For many years the inspection of parts and components by x-ray has been used in industrial applications, particularly to verify the integrity of safety critical items and to support product development. Today, the increasing use of high density “exotic” materials in complex structures made possible by additive manufacturing techniques requires the use of high-energy x-ray to fully penetrate...
The development of compact femtosecond MeV photon sources with controlled energy spread will enable powerful new modalities for active interrogation. One technique, so-called Gamma-ray LiDAR, has potential to produce a one-sided 3D image by studying the time of flight of backscattered gammas fired at a target under study. Previous experiments, including at the Idaho National Laboratory and the...
Developing methods to non-destructively determine the elemental composition of bulk materials is important in a broad range of contexts, including food and agriculture, coal and minerals processing, contraband detection, and nuclear regulation [1,2]. Neutron-based techniques are advantageous as neutrons are highly penetrating, sensitive to low mass nuclei and produce characteristic secondary...
Hair remains an invaluable biological screening material due to its numerous advantages over urine, blood, and other biological screening materials. Its intricate physico-chemical properties provide a wealth of insights into a person’s diet, origin, and even health. Its ability to store chronological exposure to xenobiotics for application in forensic toxicology and drug abuse studies, its...
