Considerations When Generating Rock Events¶
Flux (Dk2Nu)¶
- expanding the flux window, building off previous entry
- reuse file entries
- setting minimum estimated max weight
- what to do when max weight exceeded
GENIE proper¶
- use "rock box" to limit volume considered based on nu ray energy
(asymrock not yet working)
(does "efromw" flag work ?)
- example for standalone
gevgen_fnal
- run rays backward to fixed z position (upstream of any volume of consideration)
Geant4¶
- kill particles pointed away and outside some minimum distance from surface
- tradeoff on killing early vs. possible neutron generation by particle
