Thanks for replay!
Sorry, my bad. Its Helium.
About first questions: all information you can get from SRIM code.
Simulation was done according to task (He ions in W target). First pic destributions of ions in target, second pic ions pass(red) stopped ions(white).
"Your irradiation time depends...
1. The purpose of the irradiation is to study cross-sectional (along the ion pass) radiation damage in terms of in-plane stress, strain and interplanar distances.
2. Radiation damage effect, the effect of trapped helium from the point of view described above.
Hi everyone,
How to calculate time of irradiation (t) if you know:
Type of ions: H
Target material: W
Ion energy: 2.5 MeV
Ion current: 100 µA
Ion fluence: 10^16 ions/cm^2
Thank you!
