Question on Partran Scattering and Stripping Options [SOLVED]

[ZY Song]

I have a question about the scattering and stripping options in Partran. I could not find a clear description of their application scenarios in the user manual. Could you please explain when these options should be used and what kind of physical effects they are intended to model? Additionally, should these effects be considered only under certain vacuum conditions, or are they mainly relevant in specific application scenarios?

Have a look about the 'GAS' command in manual

Dear Didier
I think my previous question may not have been very clear.
After reading the manual, I understand that the gas stripping and scattering options in multiparticles need to be used together with the GAS command. However, I am still not sure about the practical application scenarios of this command.
Is it mainly intended for cases where gas is intentionally introduced (e.g., gas injection), or is it also used to model residual gas effects in general beamline simulations?

[Didier]

I’ve mainly used these features for low-energy light-ion lines. In particular, I was able to verify that the beam stripping measured after gas injection into the line was consistent with the simulations. It’s more difficult to verify this for beam scattering. But in principle, it should work in plenty of other applications.

Didier
