  1. Unified HEROS Code for Heat and Ion Implantation Profile Calculations under IFE Conditions Qiyang Hu1, Jake Blanchard2, Shahram Sharafat1, Nasr Ghoniem1 1:UCLA 2: UWM

  2. Models and applications (current approach) HAPL Chamber Analyses Thermo-structural Models Ion Effects Models Exposure Experiments

  3. A unified approach: comprehensive HEROS code • Inputs: • Threats • Ion spectra • X-ray spectra • Neutron spectra • Laser intensity • Properties • Outputs: • Temperatures • Stresses & Strains • Crack depth • Ion concentration • Ion cluster sizes HEROS MC A. Takahashi’s Poster Surface M. Andersen’s Poster

  4. Unified HEROS Implementation Plan • Short Term • Ion Implantation • Temperature • Single Cycle Stress and Strain • Medium Term • Multiple Stress Cycles • Ion Clustering (single cycle) • Long Term • Damage (dpa) • Surface Cracking • Sputtering

  5. Ion Implantation and Heat Generation Ion Spectral: Perkin’s data 350MJ Target Calculating Arrival TimeR = 10.5 m Calculating Stopping Power(by SRIM & Excel) Unified HEROS

  6. Ion Profile:

  7. Heat Rate (Q’’’) At the surface Over the depth

  8. Heat by X-rays Perkin’s data

  9. Transient Temperature Profile Target: 350MJ, 10.5m Ref Temperature = 600CAdiabatic Boundary at x = 0

  10. Stress Analysis: (Perfect Plastic) For tungsten: E = 411GPa  = 0.28  = 4.510-6 /K s= 550 MPa

  11. Stress and Strain Calculations Strain Stress

  12. Summary • HEROS unified for thermo-structural models • Ion implantation • Heat generation • Mechanical response • Future work: • More complex stress-strain behavior • Multiple shots • Comparisons to more experiments: (RHEPP, Dragonfire etc.)
