−
** Currently it looks like no tritium issues with current design
 
−
** Radiator position is currently 16cm upstream of the mahnet upstream steel face
 
−
** 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
 
−
** Pavel's new geometry has tapered steel upstream of absorber in X and Y - needs
 
−
** Also taper in Y in Cu/W in magnet area - we will just use the exit size all the way through
 
−
** New files with fine granularity in absorber high energy absorption areas are available - Hovanes will convert to usable files for ANSYS
 
−
** New files for complete CPS power absorption available and Hovanes will convert
 
−
** Tim will run new ANSYS models for the complete assembly
 
−
** Tim learning FLUENT to verify cooling assumptions
 
−
** There needs to be a collimator upstream of radiator
 
−
*** 1cm diameter hole
 
−
*** 15 cm deep in Z
 
−
*** OD of ? cm
 
−
*** About 10W absorption - no active cooling required
 
−
*** 80% W, 20% Cu
 
−
* 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
 
−
* Looked at 2025 install with MRI magnet and 2026 without MRI magnet just to show feasibility
 
−
* Lead brick painting awarded - should be complete by end of September

* Magnet Power Supply on schedule to be delivered March 2025
 
−
* Magnet DeGauss test still scheduled for summer
 
−
* Tim still writing and analyzing copper and tungsten thermal cyling data for ERR reply to Patrizia - hopefully a draft in 2 weeks
