  1. 97. Overview of Radiation Materials Science and Radiation Damage Modeling
    David Senor (Pacific Northwest National Laboratory)
    06/11/2023, 13:45
    Invited Oral

    To understand and reliably predict the irradiation performance of materials, it is important to understand the fundamental effects of radiation on materials at the atomic scale. At the most basic level, radiation effects are caused by the creation of point defects including interstitial defects, substitutional defects and vacancies. Point defects are created when an incident particle or a...

  2. 134. Irradiation damage of diamond by ion implantation
    Dr Masahiko Ogura (AIST/Japan)
    06/11/2023, 14:15
    Invited Oral

    Diamond is expected to be applied to next-generation power electronics and quantum sensor, due to its excellent and unique physical properties. As in the field of semiconductor device industry with other materials, ion implantation technology is indispensable for realizing diamond devices because of its design flexibility, where depth and concentration can be controlled by ion energy and...

  3. 90. Capabilities of the FLUKA particle transport code for the design and operation of high-power targetry systems
    Dr Vasilis Vlachoudis (CERN)

    Contributed Oral

    FLUKA [1-3], developed and maintained by the FLUKA.CERN Collaboration, is a general-purpose code for the Monte Carlo (MC) simulation of radiation transport. It is capable of accurately accounting for the transport and interaction of over 60 particle species (photons, leptons, hadrons, and ions) in complex material geometries on a broad energy range, from the keV (meV for neutrons) up to the...

  4. 22. Measurement of displacement cross section for high-energy protons and future plan for material damage using 0.4 GeV protons at J-PARC
    Shin-ichiro Meigo (J-PARC/JAEA), Dr Shin-ichiro Meigo (JAEA/J-PARC)
    06/11/2023, 15:00
    Contributed Oral

    Material damage index of displacement per atom (dpa) is calculated by the particle flux and the displacement cross section. Since the experimental data of the displacement cross section was scarce, the measurements using protons were conducted, and so far, the experimental data of protons up to 30 GeV have been obtained in J-PARC and other Japanese facilities. The displacement cross section...
