Rakitha : A Prototype collimator for PREX (Iteration-1) elog-2908

Dustin : Preliminary comparisons between G4 and MCNPX neutron prodution elog-2909

  • Present:

Rakitha, Seamus, Dustin, Kent, Paul, Guido, Bob, Lorenzo


  • MCNPX Simulation first updates
    • MCNPX neutron yield estimation for neutron is factor of 2 high at energies 5-20 MeV compared with Geant4 results.
    • Similar comparison with tungsten will be done soon
    • Current simulation used an electron beam. To minimize the EM effects, same simulation study will be done using a photon beam and compare with Geant4
  • PREX Prototype Collimator
    • Current collimator lenght needs to be shorten to fit in the PREX setup.
    • Increase the DS bore radius to minimize the slit scattering


  • From Last Meeting
    • Beam parasitic studies
