SUMMARY

This discussion focuses on calculating the cascade volume in a steel alloy subjected to ~1 MeV ion irradiation, specifically with a Z value of ~25. The user is analyzing the electronic stopping regime with a Primary Knock-On Atom (PKA) energy of ~14 keV, resulting in approximately 10 keV for damage energy. The user has derived a cascade volume of 50 nm³ using a maximum cascade temperature of ~10,000 K but questions its validity. They seek guidance on whether to perform calculations from scratch or utilize existing simulation tools like Geant4.

PREREQUISITES
  • Understanding of ion irradiation effects on materials
  • Familiarity with Primary Knock-On Atom (PKA) energy concepts
  • Knowledge of simulation tools such as Geant4
  • Basic programming skills for implementing calculations in Matlab
NEXT STEPS
  • Research the application of Averback's equation in cascade volume calculations
  • Explore the capabilities of Geant4 for simulating ion irradiation effects
  • Investigate existing Matlab codes for calculating cascade volumes in materials
  • Study the TRIM software for insights on ion interactions with matter
USEFUL FOR

Materials scientists, nuclear engineers, and researchers involved in ion irradiation studies and cascade volume calculations in steel alloys.

So I was wondering if anyone could help me out. I am trying to find a way to calculate the cascade volume in a steel alloy undergoing ~ 1 MeV ion irradiation ( Z ~ 25). For this analysis I will be looking at the electronic stopping regime with PKA energy of ~ 10 keV. Not sure what to do after calculating the PKA energy.
 
Do you have to do it from scratch, or can you check what common simulation tools like Geant4 are doing?
 
I have to do it from scratch since my programming abilities are very limited. I actually came up with a volume analytically using a maximum cascade temperature of ~10000 K, but the volume seems small ( V = 50 nm^3 ). Since I am trying to calculate the volume mid ion range, (about halfway through) I think using Averback's equation from TRIM results will not be helpful. My PKA energy is actually 14 keV which leads to approximately 10 keV for damage energy. You wouldn't happen to know of any Matlab code to handle this would you?
 
I would use some existing software package, or at least see what they did (there should be some references explaining that, I just don't know where).
 
Ok, thanks for the replies.
