FE analysis of ITER Bolometer for thermal loads
FE analysis of ITER Bolometer for thermal loads

  • Determination and evaluation of the thermal loads
    • thermal radiation from the plasma and the neighbouring divertor modules
    • heat conduction from the vacuum vessel
    • nuclear heating
  • Investigation and implementation of temperture dependent material properties
  • Calculation of thermal displacements
  • Local analysis of the collimators line-of-sight and stresses in the detector foil
  • Investigation of the change of the screw pretension due to different coefficients of thermal expansion·of the connected components and the screw itself
  • Investigation of alternative materials for selected camera components in order to minimize thermal deformation and stresses
  • Detailled evaluation of the heat fluxes at a variation of the heat transfer coefficients and materials
