I need to calculate the flux of "extra" electrons produced by enviroment electrons in Europa environment. I have beed using GRAS to do my simulations and can calculate fluxes "to", "from" and "between" volumes but I cannot directly calculate the flux of the new electrons that might appear due to e radiation.
Questions: 1. Can I ignore the secondary electrons from electron sources and consider electrons produced by protons dominating (I know how to calculate secondary electrons when I have ion source:-)?
2. Can I estimate the secondary flux by subtracting "in" flux from the "from" flux? I understand that the logic is not flawless as some incident electrons might not leave the volume.
Thank you, Sveta
