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 according to a specified file extension.

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