Feasibility study of compact Neutron Resonance Transmission Analysis using a linac, a fusion-based neutron generator, and an isotopic source
… beam line facilities with kilometer-long accelerators. This work explores feasibility of compact NRTA configurations using a linear accelerator (linac), fusion-based neutron generator, and isotopic source. Monte Carlo simulations show that these configurations trade off between complexity …

Design and performance of a compact high-energy computed tomography system for the study of metal solidification
… X-rays photons were produced by a compact 6 MeV linear accelerator (linac) with an average energy of 1.3 MeV. The linac was pulsed at a rate of 180 Hz, with a 4 Rs pulse duration. The photons were emitted from a 2-mm spot in a 320 fan-beam configuration. A 128-channel detector system, placed on …

Real-Time Radiation Detection within the Gastrointestinal Tract
… 2100 Curie Cobalt, 320 kV X-ray irradiator, linear accelerator (LINAC) with 6, 10, and 18 MV beam qualities, and a neutron beam sourced by a 5.7 MW nuclear reactor. An in vivo study was then performed in which the encapsulated diode was placed in a swine’s stomach, and 110 kVp X-ray images …

An optical computed tomography scanner for three dimensional gel dosimetry of radiotherapy dose distributions
Clinical radiotherapy treatments using linear accelerator (linac) generated megavoltage xray beams are planned using computer models that calculate patient specific three dimensional (3D) radiation dose distributions. Treatment planning system (TPS) calculated doses are evaluated by clinicians to …

Medical Isotope Production of Actinium 225 By Linear Accelerator Photon Irradiation of Radium 226
… a high-energy photon spectrum (generated by a linear accelerator or LINAC) to irradiate a sample of Radium-226 (half-life 1600yrs). The photo-neutron reaction liberates neutrons from Ra-226 atoms leaving behind Radium-225 (half-life 14.7 days). Ra-225 decays naturally through beta emission to …

RADIATION CHEMISTRY IN PRESSURIZED WATER NUCLEAR REACTORS: H2 GENERATION BY 10B(n,α)7Li, AND THE REACTION OF BORATE WITH •OH
… Notre Dame Radiation Laboratory’s 8 MeV electron linear accelerator (LINAC) was configured to perform pulse radiolysis with pulse widths between 4ns to 20ns providing doses between 5.5 Gy and 62 Gy. High-energy electrons from the LINAC interact with the borated solution which has been …
