MAGNET AND SHIELDING MODEL (Josh)
- Cu core cooling channel and inner structure - fixed inside magnet
- 180 degrees circular turn - rectangular does not give this radius of turn
- Actions:
- Need to work out tolerances to see all fits
- Thermal expansion
- Lifting feature
- 180 degree turns - need special attention when stacking shielding blocks
- Shielding stacking - 1.8 cm gap since magnet end does not align with a number of blocks (cm vs inch)
- Action: to continue stacking: leave the gap as is - until know what actual size of bricks will be
- filling of gap for shielding reason, not structural reason (different options available to fill the gap)
ENGINEERING/DESIGN (Steven L.)
- Work in ongoing
CPS POWER ABSORPTION (Bogan)
- W has essentially no thermal expansion
- Deformation risk for Cu core due to high temperature (~400-500 degC)
- narrow beam channel and 40cm long piece with width only few mm
- can't afford deformation of inside slot (where beam is) - need beam alignment up to 1mm
- should look at this and see how to include some room for motion - system is very compact
- Actions:
- Steven L. and team will start looking into this
- Josh send step file to Steven
NEXT MEETING: FRIDAY 31 JULY AT 11:00AM (ET)
