Dustin : Neutron energies exiting material: MCNPX versus G4 for Cu and W elog-2919

  • Present:

Rakitha, Dustin, Paul, Lorenzo and KK


  • The agreement of neutron production and enrgy spectrum between MCNPX and Geant4 is very good as seen from the analysis summary in the elog-2919
    • As a further step Dustin will do the Neutron simulation for Copper-Tungsten 70 compund.
  • What is the best possible benchmark for the integrated radiation from PREx-II?
    • KK proposes that we should come up with a design and provide it to JLab engineers to come a conclusion. If there is a radiationissue can we come back to it later?
    • From last week discussion with Bob, he thinks we should benchmark with a standard hall A experimental setup (ex HAPPEX target and collimator)
    • This issue is mainly related to the neutron production at different sites from electron interactions and these neutron damaging various equipments in the hall.

    • Beam parasitic studies
