Dear fluka users,
I have tried to study the secondary electron production using fluka.
For this I have used a carbon(C-12) beam of energy 1200MeV. The
position of Bragg's peak in my medium is near 2.5cm. Interestingly, I
have found that production of secondary electrons is maximum near the
starting edge of the sample rather than at Bragg's peak (where the
beam looses maximum of its energy). I have come to a conclusion that
though the energy loss by the beam is maximum at Bragg's peak, loss
per interaction is less than the ionization potential. The 2D images
of energy deposited by the Carbon beam and the secondary electrons
are attached along this mail. Please help me to understand the
physics behind this (or, some relevant references regarding this
topic)
Thanks in advance
