Dear Chris,

The gas mixture was selected to mimic the properties of the Ne-based mixture.

So it is pretty much the same (blue points on the attached pictures):

Hi folks,

we are still running with Ne in the sims. I don't think it makes a big
difference for the G4 sims themselves but the drift velocity:

double tpc_drift_velocity_sim= 8.0 / 1000.0;  // cm/ns   // this is the
Ne version of the gas

might be a problem if it is very different.

Chris
