Integration sequence:

  • Loaded Modules on Rings
    • Welding, QC testing
  • Load Services into ¼-shell
    • Transfer ¼-shell to integration tooling
  • Load Rings into ¼-shell
    • Transfer Rings to integration tooling
    • Integrate Rings into ¼-shell
    • Welding, QC testing
  • Integrate two ¼-shells
    • QC testing
  • Package, ship 


19-0 1/4-shells in B33 cleanroom:


Past presentation: Integration Tooling and Plan at SLAC 8 Nov 2021.pptx


Next steps:

  • Prepare for 19-0 (Drafting - setup with dummy rings and linear slide)
  • Finalize design/drawings of tables

Linear Rail

Selection of a linear rail to test for 19-0/1.

Requirements (preliminary):

  • Cleanroom compatible
  • Load: ~1kg
    • weight of loaded Ring and HF (~1kg, not in SE)
    • operator load - handling/sliding linear rail
      • installing HF onto rail fixture while extended - robust to operator error
  • Range: ~0.4m (retracted) to ~0.9m (extended)
    • extend by at least 0.5m (to make ring engage far side 1/4-shell)
    • retracted length ~0.4m (to not overhang edge of table)
  • Precision:
    • Line up threaded holes in Ring with thru holes in 1/4-shell
      • 2mm pins, 2.4mm clearance holes → ~0.4mm dia. clearance shared between assembly and manufacturing tolerances
      • 19-0/1 prototype: linear rail, HF bolted on. no other adjustment. unbolt/rebolt to make small adjustments via oversized holes
        • Bolt together, slide in rail, check misalignment, slide out rail, adjust if required
        • Bolt together, install taper pins, slide in rail, install fasteners
