MVD track point simulation

Performance

• Mechanical model (CAD) as STEP-file
• CAD converter: STEP-file to Root-format ( TGeoManager )
• Simulation: MC tracking (Geant4) including B-field and full material budget
• Particle source: Isotropic, point-like source

Input parameters

• Particle species: (Proton, Pion +/-, Lambda, ...)
• Particle energy: [0.1 ... 5.0] GeV
• Origin of the particle source: 0;0;0) or any displacement
• Number of events (typically 520,000 -> 14 h for simulation)
• Polar angle: 2° < Omega < 160°

Analysis

• Average number of MVD points / track
  • Full MVD / Barrel part (Theta > 45°) / Forward part (Theta < 45°)
    

• Spatial distribution (Theta-Phi) of MVD points / track
  • Mapping for all tracks / Mapping only for regions with less then 3 MVD points / track in average
    

• Angular distribution (Theta) of MVD points / track
  

Output

• Compare different detector versions
• Study performance for particle specias at different energies
• Study performance for differebt particle species, in particular charge conjugated particles
