Meeting Time and Place
Tuesday, June 04, 2024, 1:00pm Hall D Counting House
- Invited - Hovanes Egiyan, Stephanie Worthington, Keith Harding, Pavel Degtiarenko, Tim Whitlatch, Eugene Chudakov, Josh Ballard
Agenda
- Review minutes from last meeting https://halldweb.jlab.org/wiki/index.php/May_07,_2024_KLONG_CPS_Design_Meeting
- Review new basic 3D model
- Core Section update
- New radiation levels? Pavel
- Layout of magnet and components (Stephanie/Keith)
- Vendor coming next week to demo system
- possible moving plan https://www.aerogo.com/products/air-caster-rigging-system/
- Concerms with dust/contamination - Tim to work with ES&H
- Baseline KLF schedule
- Power supply status - On order, due March 2025
- Magnet update (Josh/Stephanie)
- Radiation levels at coils 2.E+4 Gy for a 10000 hour run
- Plan on using copper dump skid to cool magnet - is it adequate LCW?
- Copper cooling update -
- Status of brazing sample test media:CPS Absorber cooling test sample.pdf
- Lead brick painting is awarded and due back in September
- DeGauss test summer 2024
- June - items due from ERR
- Thermal cycling of tungsten and copper write up - in work - ready in 2 weeks (Tim)
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
- 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
- Core assembly coming together
- 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
