 ====== HepSim manual ======

[[http://atlaswww.hep.anl.gov/hepsim/ | HepSim]] is a public repository with Monte Carlo simulated events for high-energy physics (HEP) experiments.
The [[http://atlaswww.hep.anl.gov/hepsim/ | HepSim repository]] was started at ANL during the US long-term planning study of the American Physical Society’s Division of Particles and Fields (Snowmass 2013) with  the goal to create references to  truth-level  MC records for current and future experiments. Event data samples are created using:

  * BlueGene/Q supercomputer of the Argonne Leadership Computing Facility ([[hpc:bghep:start|BG@HepLib]] library)
  * [[https://portal.ci-connect.net/|OSG (Open Science Grid) Connect]] ("FutureColliders" project). 
  * ATLAS Connect virtual cluster service ("ATLAS CI" project)
  * Argonne’s Laboratory Computing Resource Center (LCRC) ("HepSim" project)
  * ATLAS Analysis support (ASC) cluster at HEP/ANL

The file storage is provided by:

  * STASH2 storage at OSG CI Connect
  * FAXBOX storage at ATLAS Connect
  * [[https://www.nersc.gov/users/science-gateways/|NERSC science gateways]]
  * MC.HEP server at ASC ANL

This repository was created following
the guidelines and principles of the
[[http://www.energy.gov/sites/prod/files/2014/08/f18/DOE_Public_Access%20Plan_FINAL.pdf|DOE Public Access Plan]]
for unclassified and otherwise unrestricted scientific data in digital formats.

Here are several links to extending this Wiki for particular detector-performance topics:
 

  * [[fcs:fcchh:|FCC-hh detector studies]] - explains how to analyses data for FCC-hh detector studies
  * [[fcs:sid:|SID detector studies]] - explains how to analyses data for the SiD detector (ILC)
  * [[fcs:cepc:|CEPC detector studies]] - shows some results with full simulations for CEPC
  * [[fcs:eic:|EIC detector studies]] - shows some results with full simulations for EIC
  * [[vlhc:hcal|HCAL studies]] explains how to analyse ROOT data after fast detector simulations used for FCC studies
