Introduction
Fission reactions produces fragments of different energies, these fragments interact with the medium and causes ionization. Fission fragments stopped by the medium in different ranges, the range is dependent on the following :
1- Mass of fission fragments
2- Charge.
3- Kinetic energy gained after the fission reaction.
4- The medium surrounding the fission fragments.
- The aim of this study to calculate the number of electrons produced by the fission fragments.
In this study the fission fragment will treated as ions without any electrons surrounding the nucleus.
Ion Interactions with matter
As the ion is traveling through the material, it causes a number of interactions because of Energy loss, like energy struggling , charge exchange, and multiple scattering. those interactions help in determining the energy dispersion, range and emittance. 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.
