Agenda

• Review minutes from last meeting https://halldweb.jlab.org/wiki/index.php/April_09,_2024_KLONG_CPS_Design_Meeting
• Review new basic 3D model
  • Copper Absorber translatable model to Fluka?
  • New radiation levels? Pavel
  • Layout of magnet and components (Stephanie/Keith)
    • Combined support for magnet and absorber
    • possible moving plan https://www.aerogo.com/products/air-caster-rigging-system/
• 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?
• Copper cooling update - media:CPS Absorber cooling 8 offset holes.pdf media:CPS Absorber cooling 8 offset holes_2.pdf
  • Perform Brazing test
  • Lead brick painting should be out for bid this week
• DeGauss test summer 2024

Minutes

• Reviewed minutes from last meeting
• Translation from NX to Fluka were largely unsuccessful
• Need to give x, y and z coordinates of shielding around the absorber to Pavel to rerun Fluka model (Keith H.)
• Get Pavel magnet dimensions to rerun Fluka (Stephanie)
• Magnet will be supported on same support as absorber/shielding
• Discussed use of air casters to move the CPS assy around during installation and moving after commissioning
  • About $35K to procure system
  • It will give us much ore flexibility during assembly
  • Need to rent a portable compressor (200 SCFM) with 2" air lines
  • seemed to be acceptable plan, we will pursue this further
  • Concerns with radioactive dust (contamination)
  • Get with ES&H/RADCON to discuss mitigations
  • Will see if anyone else at the lab has used this or owns a system - no go
• Discussed Project Gant chart being developed for the entire KLONG project -
  • will send a preliminary out soon (Tim)
  • Will include schedule and manpower needs
  • Keith H. will most likely have less time in the near future to work on KLONG
• Brazing test planned for absorber
  • 8" Z length 1/2 of the absorber
  • three 3/8" supply and return per half
  • tubes brazed into section with no water exposed joints inside shielding
• Magnet
  • Still need to determine if less expensive resin can be used
  • All water exposed joints will be outside shielding
