Question Stepsize Limit depending on logical volme

Hi All,

If this question has already been answered, I'm sorry for posting the question twice.

The collaboration I am working with has created a Geant4 simulation of neutron induced fission using a Time Projection Chamber (TPC). The TPC can be field with what ever gas the user wants, and contains a fissionable source at the center. To ensure faster simulations we do not include the electric field inside the Geant4 simulation (all process that deal with the electric field are handled in a standalone simulation). Meaning that the pad plane (consisting of 3000 hexagonal pads is reproduced several times throughout the TPC)

We want to be able to control the step size of the particle depending on the radiation length of the material the particle is traveling through. I was able to do that by using G4UserLimits and setting the limits to the specific G4LogicalVolume.

When I set the step size, I notice that all my energy loss is due to steplimit instead of ionization like it should be. But when I do not set the step size the energy loss is due to ionization.

Is there a way to set the max step size but still have the particle lose energy due to ionization and not step size?

Thanks for your advice, Remington Thornton
