Revision as of 18:25, 24 February 2020
DISCUSSION MATERIAL
- Update from CPS beamline meeting
- Update from KLong and GlueX collaboration meetings
ACTION ITEMS
- Remind Radcon about sending numbers
- CPS radiation simulations: additional tests to finalize CPS optimized geometry (see emails)
- Hall D - prepare a sketch model of magnet
- TCS: for Q2=5 GeV2 want reliable extraction of CFF and show that one can have a good measurement in Hall A/C
SUMMARY NOTES
RADIATION SIMULATION
- discussion of a number of different simulations carried out to optimize cost, material, dimensions - done in two ways: 1) geometry, material, layering, and 2) pure material
- If replace all tungsten with lead, then prompt radiation significantly worse, but activation levels still looks good
- Replacing tungsten by lead in the backward region has reasonable prompt and activation levels depending on how much lead is used - lead below z=0 seems a good compromise
- Having a lead "frame" outside (2.5 cm top, 5cm bottom) helps to reduce radiation levels even further
