I am a beginner of SRIM and I have some questions .
- I want to simulate the ionization of α in air using TRIM, but the target density makes me confused.It is well known that the density of air is 1.29 g/cm^3,however,if I tick the gas option ,the desity is 1.57E-03,if I don’t tick the gas option ,the density is 1.1268. I want to know how to set the density?Can I change the density to 1.29 and tick the gas option? What is the difference between ticking or not ticking the gas option
- How to set “Total number of ion"?The more the better?What factors should be considered?
