Crystal Grain Size and Temperature Annealing


I am attempting to study DPA as a function of beam type and kinetic energy of SiGe. Am I able to manipulate the crystal grain-size of my geometry in Flair? Also, I’m wondering if I could study temperature as a function of DPA to observe annealing effects.

Dear @s.r.hall76331 ,

FLUKA is not capable to simulate crystal structures, only homogenous compound materials can be defined.

The DPA and temperature both depend on the beam parameters and linearly scale with the beam intensity, with the assumption that the specific heat is constant (which is not).

For an exact temperature calculation a separate, (for example) finite element simulation is required. See: Energy deposition and associated temperature - #5 by adonadon
