Detailed Description

Run action class

It accumulates statistic and computes dispersion of the energy deposit and track lengths of charged particles with use of analysis tools: H1D histograms are created in BeginOfRunAction() for the following physics quantities:

• Edep in absorber
• Edep in gap
• Track length in absorber
• Track length in gap The same values are also saved in the ntuple. The histograms and ntuple are saved in the output file in a format accoring to a selected technology in B4Analysis.hh.

In EndOfRunAction(), the accumulated statistic and computed dispersion is printed.
