Hi Daniel,

The quickest way to get the space environment flux spectra into your simulation is to use the GPS macros created by SPENVIS for its version of Mulassis. These GPS macros you can then add to your own software (the /analysis/normalise factor must also be included to normalise the results of the simulation to those of the environment, but it may require adjustments to account for variations between the geometry of the GPS source in your own code and what's in Mulassis).

The quickest way to check that the G4 simulation is giving comparable results to SHIELDOSE is by running the SHIELDOSE slab geometry and the corresponding Mulassis Slab geometry for a given shielding thickness, you can then compare the dose results directly with the Mulassis simulation on SPENVIS.

As for the Physics: the SHIELDOSE model does include nuclear interactions for protons; for electrons the "em" physics should be sufficient; to a reasonable approximation the "em" physics is sufficient for protons as well, but you can add "binary cascade" to include nuclear interactions to the results.

Regards, Hugh
