as I need to introduce an electric field in a ionisation chamber, I previously made some tests in order to be sure what I do is right.
I've modeled a box full of vacuum, in which I've implemented a uniform and linear electric field toward z > 0 axis. I have shot particles along x > 0 axis and compared data with and without the field.
First particles shot are 1500keV alphas : their trajectories is deviated toward z > 0, what is physically expected.
Second particles shot are 100keV electrons : their trajectories is deviates toward z > 0, whereas it is physically expected that the deviation occurs toward z < 0 according to negative charge of e-.
Last particles shot are 100keV neutron : no deviation, what is physically expected.
I've made a visualisation of trajectories : alphas trajectories are drawn in blue and electrons trajectories is red, what is expected with geant4.
Did I miss something, explaining electrons behaves like positively charged particles?
