	Geant4 is adjusted to have a chamber that contains Ar (90 percent) ands CO2 (10 percent). as the beam runs, the fission fragments are produced but the effect of the ionization does not appear, i.e there are not any electrons tracked by geant4 after ionizing the gas by the fission fragments. the follwing is the result of a 10 MeV neutron beam fired on 1 um Th target twice, the first time 1M neutrons fired and the 2nd 2M neutrons fired.

 The previous interactions take place in gas chamber of the detector and produce electrons.
 This electron multiplication occurs inside an electric field area, the electric field is responsible for collecting the electrons, so the detected total charge density of the electrons depends on the electric field.

-To track the electron charge produced through the ionization, the fragment itself should be fired on Ar-CO2 target, then we check the track. since unfortunately having the electrons simultaneously from the fission event needs more search (may be new programming for steppingVerbose to tracking Verbose 3 for the 2nd secondaries)
