Detector descriptions
Here we describe available reconstruction tags used by HepSim. All detectors can be found in Detector description page.
Data are reconstructed using the so-called reconstruction tags, which can have either “rfastXXX” (fast simulations) or “rfullXXX” (full simulation and reconstruction) name, where XXX is a number. Each tag is reconstructed with certain detector plus some optional parameters for simulation and reconstruction.
You can find detectors that correspond to a given tag using RecoTag page.
Fast simulations
Fast simulations use Delphes.
| Tag name | Detector description | Documentation | Available data |
|---|---|---|---|
| rfast001 | FCC-v1 proposed detector | description | find=rfast001 |
| rfast002 | FCC-v2 proposed detector | description | find=rfast002 |
| rfast003 | CMS-like detector | description | find=rfast003 |
| rfast004 | ATLAS-like detector | description | find=rfast004 |
The file format is ROOT. Look at this description.
Full (Geant4) simulations
Full simulations use the SLIC software. The geometry files with full detector descriptions are here.
Each tag corresponds to a certain detector, and other way around. You can find the detector name using a tag as this
http://atlaswww.hep.anl.gov/hepsim/lookup.php?info=[TAG]
this will print the detector name. Instead of [TAG], use the detector name to determine the tag. Here are the examples:
Find the detector that corresponds to the tag “rfull009”:
http://atlaswww.hep.anl.gov/hepsim/lookup.php?info=rfull009
Find the tag which corresponds to the detector sifcch8:
http://atlaswww.hep.anl.gov/hepsim/lookup.php?info=sifcch8
In Linux, you can retrieve this info as:
curl -s http://atlaswww.hep.anl.gov/hepsim/lookup.php?info=rfull009

The output file format is LCIO. The files can be read as explained here. To view geometries using ROOT geometry package, run these commands:
TGeoManager::Import("detector.gdml"); gGeoManager->GetTopVolume()->Draw("ogl");
where “detector.gdml” is the detector geometry to be downloaded from this table (after gunzip command).
