  1. 14. Computer Simulation of Radiation Damage in Materials
    Dr Ram Devanathan (Pacific Northwest National Laboratory)
    2019-12-11, 11:30 a.m.
    Oral presentation
    We present an overview of computer simulation methods used to study radiation damage from the atomic to the continuum scale. Within the framework of multiscale materials modeling, the study of irradiation damage and associated materials property degradation has required modifications tailored to the application. Particle irradiation damage in accelerator targets begins at the nanometer scale...

  2. 17. Irradiation induced failure investigation of NT02 graphite target fin through numerical simulation
    Dr Sujit Bidhar (Fermi National Accelerator Lab)
    2019-12-11, 11:55 a.m.
    Oral presentation
    Some of the NT02 target fin made up of isotropic POCO graphite grade has developed crack and fractured after few years of operation. The highly energetic pulsed proton beam with small beam sigma would create thermal stress wave as well as radiation damage such as displacement damage, void formation, swelling, gas formation among few. A complex interaction of dynamic loading due to beam,...

  3. 5. Calculations of damage energy spectra of nuclear reaction products and plan for displacement damage cross section measurements using 120 GeV protons at FNAL
    Yosuke Iwamoto (Japan Atomic Energy Agency)
    2019-12-11, 12:20 p.m.
    Oral presentation
    The displacement per atom (dpa) value is widely used for the index of radiation damage in materials under high energy proton irradiation. It is possible to calculate dpa values using the screened Coulomb scattering theory for incident proton-nucleus collisions and the nuclear reaction model for nuclear reaction product-nucleus collisions in the high-energy region (>10 MeV). For defect...
