Phone Meeting: Energy Losses (03/16/2009)
I have written a simple C++ program, which calculates the most probable energy losses
of particles traveling through various materials. Here is a quick explanation of the
principles and equations that I am using in my code: miham_BetheBloch.pdf
The source code of my program can be downloaded from the following link:
EnergyLossSimulationLast.tar.gz
To compile the code simply type "make" in the extracted directory.
Results of my simulation
A.) Stopping powers:
First I have calculated the mean Stopping power (S) for each target element and compared my results with the
results from ESTAR and PSTAR .
WARNING: After a while I have realized that ESTAR PSTAR data do not consider relativistic corrections
and that given Hydrogen data can only be used for gas targets.

2.) Electrons in Carbon target:
3.) Electrons in Aluminium target:
4.) Electrons in Tantalum target:
5.) Protons in Hydrogen target:
B.) Most probable and mean energy losses
Then I have calculated mean and most probable energy losses for each target. I have been also observing parameter "kappa" which determines when the energy loss distribution is Gaussian and when Landau:

C.) Energy losses in "complete" HALL A targets:
In the end I have calculated the energy losses in various targets in Hall A
