In many cases, HepSim detector simulations were done using ILCSOFT-derived software. To create full simulations, you will need to convert ProMC files to LCIO files. This is described in LCIO conversions and LCIO sections.

Many samples posted in HepSim are created with the package called “fpadsim” (Future Particle Detector Simulator“). This package is under constant development. The contributed authors of this package since 2015 are:

• D.Blyth (HEP/ANL)
• J.MacCormick (SLAC)
• W.Armstrong (PHYS/HEP)
• S.Chekanov (HEP/ANL)
• A.Kotwal (Duke)
• J.Strube (PNNL)
• J.Marshall (U.Cambridge)

The package includes packages from ilcsoft, such as SLIC, PandoraPFA, and LCSIM The simulation and reconstruction proceeds as: SLIC→LCSIM→slicPandora/PandoraPFA. This digram shows the entire chain:

The input for SLIC are LCIO files with truth-level information (“MCParticle” table). The files are created from ProMC files using the converter promc2lcio (included inside the ProMC packages, in the directory “examples”). This concept originates from the SiD detector(T.Johnson, N.Graf, J.McCormick, J.Strube), and later was re-purposed to be used for generic feature detectors, including proton pp colliders (S.Chekanov, A.Kotwal). The final step of the reconstruction is PandoraPFA (J.Marshall, M.Thomson).

To process truth-level events with FpadSim, you need a few things:

• Tag file with detector description
• Singularity image with pre-built libraries to process the tag file
