Material Data

The PEGS User Manual outlines definitions and the structure of the utility used here to create Gismo material data.  The compressed DOS executable can be obtained via anonymous ftp ftp://ftp.ne.ksu.edu/pub/robs/iegs/ipeg0001.zip. We have snarfed a copy at ftp://ftp.slac.stanford.edu/groups/glast/ground/WindowsThings/ipeg0001.zip.

The PEGS input below generates a G10 compound and represents the template used for all GISMO materials.

    PZ(2) = 12.
    PZ(3) = 4.

Only the values for each option (type, name, etc) were modified to create all other data.  All three material types were used, and energy cutoffs are the same in each material. 

• Material types
  • ELEMent (Al, Fe, Pb, Si, W)
  • COMPound (G10, Polystyrene)
  • MIXTure (Air)

• Energy cutoffs
  • Charged particle: 500 GeV (for all types)
  • Photon: 500 GeV (for all types)

• Functional operations
  • PWLF (all options left to default)
