b'Expanding PhotonuclearNovel study enables future research and computational science in photonuclear Data via High-Energy Linearreactions for isotope production for national security, medical, and Accelerator Coupled with Real- astrophysicsapplications.time Gaseous Mass Separation A ccelerator-driven photonuclear reactions are being used more frequently to support scientific discovery, nuclear security, and medical and industrial isotope production. Inadequacies in the abundance and accuracy of photonuclear data, specifically reaction cross-sections, hamper accelerator use. This research project proposed to improve the availability of measured photonuclear cross-section data and potentially nuclear data for gamma spectrometry by integrating technologies for isotope separation with isotope production. Coupling a bremsstrahlung TOTAL APPROVED AMOUNT: linear accelerator with an isotope separator has the potential to expand the library of $1,537,750 over 3 years measured nuclear data associated with energy-dependent photonuclear reactions, PROJECT NUMBER: particularly for low-yield reactions involving short-lived isotopes. This tandem technique 18P37-031 enables the isolation, observation, and collection of fission and activation products for many isotopes with half-lives under one minute. The rapid separation of decay-chains by PRINCIPAL INVESTIGATOR: mass on time frames from seconds to hours will remove spectral gamma-ray congestion Kevin Carney and improve spectral assignments and data for relative production yields for gamma CO-INVESTIGATOR: induced fission, proton and neutron reactions as a function of bremsstrahlung excitation Jared Horkley, INL energy. Bremsstrahlung irradiations provide an alternate method to investigate the production of isotopes via proton accelerator-induced nuclear reactions with significantly COLLABORATOR: less risk since the need for thin window targets are not required.Idaho State UniversityThis project had several components: (1) confirming that a low-resolution, low-cost isotope separator can adequately provide: (a) the resolution for unit mass separation of isotopes; (b) real-time detection of isotope abundances; and (c) adequately separate and collect isotopes to simplify gamma spectra from radioactive isotopes that are measured to determine reaction cross-sections; (2) reconstituting the capability to calculate cross-sections from measured reaction yield data; and (3) demonstrating the isolation of activated isotopes and capability to obtain cross-section data on minor photonuclear reaction products.TALENT PIPELINE:Ariana Foley, student at Oregon State UniversityDaryl Giglio, student at The Ohio State UniversityThibaut Lecrevain, INLGlenn T.
