Agenda / Minutes

  • Lorenzo notes that neutron flux dominates activation for materials not seeing the primary electromagnetic flux from the target.
  • Cip: will produce
    • tree of neutron hits in XY plane, from 1mm downstream of collimator
    • tree of all hits (E&M and neutron) in XY plane on the front face of collimator
    • do this for PREX first. If we have time, we will do CREX also (but, 2nd priority)
  • Our goal for the ERR
    • activation of collimator, so we can estimate radiation field around it after shielding
    • activation of the septum (coils and yoke)
    • use old pictures of activation of the collimator box, scattering chamber
      • Lorenzo's previous status
      • scale by power deposited in collimator
      • Old plots generated using 70 uA, 4x(7days, 4 days off) coulombs on target: need to scale to this number also.
