SUMMARY NOTES
SIMULATIONS
- Work ongoing
SHIELDING AND MAGNET MODEL (Josh)
- Shielding stacked up to top of magnet - plate added on top to make things level
- Openings in front and back of shielding implemented
- Flared downstream end - still need feedback from radiation simulation to finalize
- Inlet of LCW cooling water is on upstream end - in same place as beam pipe
- advantageous from radiation point of view: high energy particles go forward (few GeV based on e beam), energy of particles going backward is soft
- Next steps:
- Build rest of shield taking into account any feedback on points below
- Need for taping on front end
- Size of beam pipe and material needed - then can build around and make support structure
- Structural support of tungsten powder - need more information on tungsten blocks
- Thermal calculation for extension of core in longitudinal direction - work ongoing
ENGINEERING/DESIGN (Amy)
- Work ongoing, e.g. thermal calculations
- Action item: dimensions of beam pipe, etc.
HALL D DESIGN/ENGINEERING (Sean)
- Work ongoing on front end
PAC48 RECAP
- All comments based on close out session - report should be available soon
- Hall D/KLong:
- science case well received, some concern about higher level management coordination
- Hall A/C TCS
- Science well received
- Main comment: need for more information on experimental setup - see if experiment is possible
- one issue: GEM as part of trigger - high risk since never done before
- one possible option: find out if GEM in SRO works as done for TDIS
- Action item: Vardan present current assumptions on trigger
NPS+CPS installation - COMPLEMENTARITY
- So far no objections based on physics
NEW CPS PHYSICS EXPERIMENT IDEAS (Bogdan)
- Two photon exchange experiment - with photon beam from CPS better intensity, use secondary target downstream plus some detectors - need to work out details
NEXT MEETING : FRIDAY 11 SEPTEMBER AT 11AM ET
