• Track the cosmic ray background from surface down to underground and calculate the flux at different level of depth.
  • Validate Geant4 muon propagation
  • Establish whether to employ MUSUN in C++ as a standard, or just work with Geant4?
• Estimate the uncertainty of the cosmogenic background in different levels underground.
• Establish a standard method for each site to prevent having to re-generate the muons each time
• Continue to interact with Geant4 collaboration on the physics lists relevant to muon production of neutrons
• Link to the Fluka v Geant working group on physics issues
