Hi guys,
i have been simulating the passage of charged particles through my detector, which consist of protons, alpha particles and electrons. For the heavy particles (proton/alpha) i have assumed a straight line trajectory, since they are losing energy through ionisation and are...
Thanks Bob,
I have read that dE/dX from radiative energy losses for electrons can be approximated as E/Xo, where E is the energy of the electron and Xo is the radiation length in the material. Is this approximation valid at very high energies? i.e. 10^7 MeV - 10^10 MeV...
Hello all,
i am trying to calculate the energy deposited by high energy electrons traveling through Silicon. I am dealing with energies in the range of 10^6 - 10^12 eV. I have read that radiative losses will dominate at higher energies and the critical energy where ionization loss =...
Hi,
thanks very much for your replies. The simulation is for CCDs in space, so I am definitely dealing with primary cosmic rays. From what i gather, i need to use the Bethe-Bloch equation to determine dE/dX at all cosmic ray energies and not use the minimum ionizing energy. I also need to...
Hello all,
i am having a few problems simulating cosmic rays with a silicon CCD detector, mainly because my knowledge on particle physics is quite poor. I am simulating primary cosmic rays, which predominantly consist of single protons and alpha particles. I am treating the protons...
Hi all,
using the mass attenuation coefficient and density, one can determine the percentage of X-rays absorbed in a material for a given depth, using the Beer-Lambert Law. e.g. The intensity of a beam of 8 keV X-rays will be reduced by 68% after passing through 70 microns of Silicon...
