Tuesday, May 07, 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/April_23,_2024_KLONG_CPS_Design_Meeting
- Review new basic 3D model
- Copper Absorber geometry for Fluka?
- New radiation levels? Pavel
- Layout of magnet and components (Stephanie/Keith)
- Current Z locations media:CPS Z locations.pdf
- 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 media:KLONG Baseline Schedule with MRI_v2.pdf
- Power supply status - On order, due March 2025
- Magnet update (Josh/Stephanie)
- Can we use less expensive resin? What is the actual expected radiation levels at coils now?
- Can we use tagger magnet LCW (goes upstairs - is radiation an issue?)
- Copper cooling update -
- Status of brazing sample test media:CPS Absorber cooling test sample.pdf
- Lead brick painting is out for bid, bids due back this week
- DeGauss test summer 2024
- June - items due from ERR
- Thermal cycling of tungsten and copper write up - in work (Tim)
Minutes
- Reviewed minutes from last meeting
- Discussed updated radiation model based on latest geometry
- Keith to supply absorber geometry and steel around it to Pavel
- Stephanie gave magnet dimensions to Pavel, for coils, Cu/H2O ratio is 56/44
- Looked at Z locations in Tagger hall
- May be space to move upstream some amount if needed
- need space for Halo monitors upstream of radiator (maybe 8cm beampipe)
- Will continue with plans to use air castors to move assy
- Onish had a power supply reveiw this week, all is still on track for March 2025 delivery
- DeGauss test
- Onish collecting parts and info for reversing switch for Mag measurement power supply
- Magnet update
- Pavel will look at radiation levels to determine if less rad-hard resin can be used
- Plan on using copper dump skid for cooling magnet to utilize ALARA principles
- Pavel asked about shielding downstream of permanent magnet, we will address that in the near future. We are concentrating on the center absorber/shielding section
- Lead brick painting bids due in May 14
- June - items due from ERR
- Thermal cycling of tungsten and copper write up - in work (Tim)
