Hi, hschindl, Are there some ways to get distribution of cross section versus electrons energy for given gas, and probability of energy distribution of electrons for given electric field in the Garfield++?
Thanks very much.

Hi,
if you call EnableCrossSectionOutput
before loading the cross-sections from Magboltz, MediumMagboltz
saves a table of the cross-sections as function of energy to a text file.
In PyROOT you can do something like this:
gas = ROOT.Garfield.MediumMagboltz("ar")
gas.SetMaxElectronEnergy(200.)
gas.EnableCrossSectionOutput()
gas.Initialise()
For a quick plot you can also use this tool on the Garfield++ website:
To fill a histogram of the electron energy distribution in an avalanche you can use the function AvalancheMicroscopic::EnableElectronEnergyHistogramming
, see this example or this example.
That’s so great and convenient, many thank hschindl.
BR,
Jiechen
