A Monte Carlo Puzzle, for the SCG. Toby Burnett University of Washington. Switch to “standard” Multiple scattering/Energy loss. Motivation: we are using an old, obsolete version of G4’s multiple scattering algorithm, and we should periodically evaluate our PSF with both versions

A Monte Carlo Puzzle,for the SCG Toby Burnett University of Washington
Switch to “standard” Multiple scattering/Energy loss • Motivation: we are using an old, obsolete version of G4’s multiple scattering algorithm, and we should periodically evaluate our PSF with both versions • Here is all we have to do: G4Generator.mscatOption = false; • My observation, based on GR v9r7: CPU time increases by a factor almost 2!
A few details: who is the culprit? • From the log file: first line is our standard, second with latest G4 code.
Is it the multiplicity? replacement current It seems not!. Good luck!
