[edit] SctParSim (Aurora)

A parametric simulation is a tool to receive a detector response without detailed description of interaction of particles with matter. The simulation is the part of the Aurora project, which is a software suit for SCTF.

Implemented detector subsystems:

  • drift chamber
  • FARICH PID system
  • calorimeter
  • muon system

The parametric simulation yields the detector response in the SCT EDM format thus allowing to analyze its result in the same manner as the result of the full simulation. The tracker and the calorimeter smear particle parameters according to a Gaussian distribution, while the FARICH PID and the muon subsystem use for that purpose the results of a pre-conducted standalone full Geant4 simulations.

More information about parameterization is presented here.

How-to use the parametric simulation is demonstrated here

[edit] SctParSim (Python)

This version of the parametric simulation had written in the Python language. The main difference is that this version has the ability to draw events.

How to run and parameter description is here
