Hello,
I would like to know the number of liberated electrons along a positive ion (C3H8+ or N2+, for instance) drift trajectory in a high electric field in the (low-pressure, about 2 mbar) parent gas (C3H8 or N2). Do you know of any approach that might work in combination with Garfield++?
I don’t see this option in Garfield++, and as far as I understood, Heed, SRIM, and TRIM are not suitable here.
Maybe someone has a kind of workaround or knows what I am missing.
Are there any available ion impact ionization cross section tables?
Dear @VictorM
Garfield++ does not calculate primary ionization, but uses input from other programs such as HEED, SRIM/TRIM. Heed calculates primary ionization for leptons/hadrons, while SRIM/TRIM calculates primary ionization for ions. When you say that SRIM/TRIM are not suitable, is that because you can only simulate energy loss for mono-atomic ions with them?

My point is that I want to simulate the drift trajectory of the ion together with corresponding ion impact ionizations, or at least have an estimate on the multiplication factor of the ion on its trajectory.
I see that SRIM/TRIM may simulate the primary ionizations, but not for the drift trajectory simulated in Garfield++.
In the plot attached you see how an ion is funneled into a cell (in -z direction) where it is accelerated due to a strong electric field that is present.
In the end, I would like to know how many electrons are liberated by each ion.
