Status of PSD simulation in Shine Oleg Petukhov Institute for Nuclear Research, Moscow NA61 Analysis/Software/Calibration meeting 11.02.2014, Warsaw
PSD simulation goals • Simulate particle hits which deposit energy inside PSD calorimeter across 44 modules x 10 sections each.
Standalone PSD simulation PSD simulation is done in VMC, including: • Realistic detector geometry in C++ code or ROOT files (NML export possible) • Geant4 transport code • External generators: Shield, URQMD, etc... (input from ASCII file) • Output (energy deposition in each of 440 sections) in the ROOT file Simulations completed with PSD simulator: • Response to protons • Estimation of energy resolution • Ion interaction in beam pipe • Distribution of spectator spots • Optimization of PSD geometry Fully functional simulation in standalone mode.
PSD simulation in Shine • Development split into “Digitizer” and “Simulator” parts • Simulator suspended due to technical difficulties and lack of manpower • Digitizer to be completed by the end of February (again)
Simulator Shine integration started: • PSD simulator module LuminanceSG provided by M. Szuba, simulating with VMC. • Code from the standalone simulation copied into a development branch of Shine. • Sources available on lxplus: /afs/cern.ch/work/p/petukhov/public/Shine_sim.tgz
Digitizer Goals • Input: (simulated) calorimeter energy response (per section) • Output: PSD electronics waveforms
Digitizer Algorithm • Calibration table (date / run number dependent) • Algorithm tweaks (time bins, peak width)
