Minutes
- Reviewed minutes from last meeting
- Pavel has run the radiation and energy absorption (Fluka) for the latest absorber and shielding configuration
- Currently it looks like no tritium issues with current design
- Radiation levels at magnet coils are 2e4 gray for 10000 hrs running.
- No need for expensive epoxy ($5K per gallon)
- CTD-101K resin can be used - good for 1e6 gray minimum
- Need to check on LCW quality of existing dump copper cooling skid for magnet compatibility
- Looking at 3D model
- Core assembly coming together
- Meet with Alignment group Thursday to discus alignment/fiducialization plan
- Looked at "birthday cake" stacking of steel - need features for stacking lead and heavy concrete
- Copper absorber vacuum brazing test piece has been machined - will get tubing ready to braze in coming weeks
- Air casters for moving - AeroGo coming to Demo system next week
- Core assembly coming together
