the option "fMinimal" is used for multiple scattering step limitation, which provides accuracy and CPU performance similar to that of the Geant4 version 7.1p02;
the parameter dRoverRange used in computation of step limit by the ionisation process is set to the value 0.8.
the option "ApplyCuts" is used enabling kill of electrons and gammas produced below production thresholds for all EM processes;
specialized process for muon multiple scattering is used, this process
takes into account small angle scattering (below 0.2 rad), for large scattering angles the single scattering process is used.
the option "fUseDistanceToBoundary" for multiple scattering of electrons and positrons;
increased number of bins in physics tables - 220 (84 bins by default);
the parameter finalRange used in computation of step limit by the ionisation process is reduced
with respect to the default value 1 mm:
for e+,e- is 0.1 mm, for muons, pions, proton is 0.05 mm, for ions 0.02 mm.
