DISCUSSION TOPICS

  • Magnet and shielding
  • Hall D updates
  • Other


ACTION ITEMS

  • Analyze recent radiation simulation results
  • Make an updated Hall A/C CPS sketch (new overall dimensions, weight) for Steve L. and team to check in the model. Make sure all CPS kinematics are available to the engineers/designers. Plan to discuss with the engineering team in April 17 meeting.
  • Get suggested Hall D CPS configurations (Sean)


SUMMARY NOTES

  • Radiation simulations (Gabriel)
  • Pb configuration works in the backward region (<0cm)
  • Tungsten seems the best option for the forward region, but some more tuning may be needed, e.g. more W laterally out to 70cm
  • Tungsten may be down to ~1m3
  • Was there a low energy cut applied? What was it?


  • Magnet and CPS design (Bogdan, Thia)
  • Keeping all components on the pivot may be difficult - possible options were discussed with the engineering team. Should check in where they are.
  • About 100 tons of lead are available from SLAC. Process has started to ship ~80 tons of lead to JLab. Discussion about storage ongoing with RADCon
  • Hall D CPS
  • Tagger area in Hall D: should be fine to move permanent magnet downstream and put CPS in that position
  • Weight up to ~150 tons (few square meters) should be fine
  • Need suggested configurations from Sean
  • TCS: work on checking the impact of magnetic field on low energy (~100 MeV) particles is ongoing


NEXT MEETING: FRIDAY 17 APRIL AT 11:00AM (ET)
