Development of first prototype of IB based on “pad chips” (joint project with WP6), dimensional survey and characterization (mechanical and thermal)

Finalize design of all components for OB: Space-Frame + Cold Plate (QM), End Wheel (EM/mock-up), Conical Structural Shell (EM/mock-up), Cylindrical Structural Shell (EM/mock-up)

Development of first prototype of OB stave based on “pad chips” (joint project with WP7 and WP8), dimensional survey and characterization (mechanical and thermal)

Finalization of IB geometry (inputs from WP1 and WP2) and layout (with WP6 and WP10). Finalization of OB geometry (with inputs from WP1 and WP2) and layout (with WP7-WP8 and WP10).

  • To be defined soon
  • BP radius* OR=18mm Vs 19.8mm (WP1,WP2 and MFT)
  • Layer 0 radius Distance from BP wall
  • Middle Layer radius Material budget
  • Stave width Chip size i.e. Layer 0 radius, FPC layout
  • Stave length Layer radius, Power regulator
  • Stave overlap Chip dead zone

*Wednesday 22°:

meeting with MFT – Gines Martinez, Stephane Bouvier (convener WG5), Jean Michel (convener of WG7),…

to verify layout and installationconstraintthatdefine MFT disk innerradius i.e. beam pipe outerradius; discussion on the outcome in the WP9 meeting in the afternoon

Development of all mechanical components for IB: Space Frame&ColdPlate (QM), End-wheel (QM), Cylindrical Structural Shell (QM)

  • Planned activities
  • Space Frame&Cold Plate
  • -SF&CP construction: evaluate replacement of Carbon fleece with K13D2U (45µm), test
  • -SF&CP Polyimide pipes: continue erosion test
  • - SF&CP Connectors: define production process & material; peek (standard machining) Vs Accura Bluestone (3D print), test
  • - SF&CP alternative options micro-channels: proposal to be finalized and decision to be taken soon
  • - SF&CP + HIC: perform assembly to finalize design, test
  • End-Wheels:
  • -EW geometry: needs definition of layer radius, stave width, stave length
  • -EW openings for services: needs definition of FPC/cable and Cooling pipes routing/modularity
  • -EW I/F: perform assembly with SF&CP to finalize design
  • Cylindrical Support Shell:
    • - CYSS geometry: develop I/F with EW and with the Cage and Service Barrel
  • - CYSS design: needs structural verification, FEA

Development of first prototype of IB based on “pad chips” (joint project with WP6), dimensional survey and characterization (mechanical and thermal)

  • Planned activities
  • Production of 24 staves (Half Barrel), 48 connectors, 6 end-wheels, 48 inserts, 1 CYSS, + spares: needs design definition (QM) and new moulds production
  • Definition of assembly procedure for stave (SF&CP+HIC(FPC+Chip)), layers, half-barrel: needs procedure validation on EM,
  • Production of new jigs for assembly
  • Production of first prototype of IB stave with HIC (dummy), test
slide8

Finalize design of all components for OB: Space-Frame + Cold Plate (QM), End Wheel (EM/mock-up), Conical Structural Shell (EM/mock-up), Cylindrical Structural Shell (EM/mock-up)

  • Planned activities

4. Finalize design of all components for OB

Air Cooling Study (USA)

Cold Plate alternative options

  • Reduced power load may allow air cooling
  • Aim is to fit within current envelope of Cold Plate
    • Use Graphitic Foam to improve effective HTC of air flow; minimizes mass flow required
    • Unsure of DP
  • Measure Darcy constants for various porosity foam (pressure drop scaling)
    • Samples on order or on-hand of various pore-sizes
    • Commercial contract issued, expect results in Feb
  • Prepare Thermal Samples to determine effective HTC
    • Pressure drop test used to select porosity of foam for test
    • Build geometrically similar samples for heat load testing
  • Goal to make decision whether to proceed to full scale by April
