Simulation of detector and/or detecting material

Software packages

For a nice overview look at the Indico page of an RD51 simulation workshop.

neBEM - nearly exact Boundary Element Method

Computes the electric field and potential in nearly arbitrary 3-dimensional geometries taking the presence of conductors and dielectric media into account: official website

Alternative to a Finite Element Method (FEM) tool like ANSYS where Poisson's equations can't be solved in a strict mathematical way.

ANSYS

FEM calculation tool to e.g. calculate electric field maps.

Garfield/Garfield++

Garfield and Garfield++, the C++ portation.

Magboltz

Calculates the gas properties used by Garfield simulations: official website

GEANT4

Simulates particle interactions in a detector (with custom geometry and materials): official website

• These introductory slides from an MC-PAD training event on GEANT4 at DESY give a good introduction.
• There is a way to use the GEANT4 libraries within a Python environment: g4py. These two slides describe the functionality of this binding.

NEST - Noble Element Simulation Technique

Addition to GEANT4 to correct calculations on interactions in noble gases (also in liquid phase), especially at low energies: official website

Detector simulations in the Detector R&D group

• GEANT4 simulation of the XAMS setup (Rolf)
• GEANT4 simulations for Tipsy (Annemarie)
• GEANT4 simulations for TPC
• GridPix (Wilco, Stergios)
  • eletric fields and grid geometry
  • electron transport in CO2/DME
