  1. Beam Pipe Support Structure (BPSS)Services Interface and AssemblyFinal Design Review, April 2003 E. Anderssen, N. Hartman, A Smith, LBNLS. Coelli, Milano

  2. Beam Pipe Support Schematic of Beampipe, Support Structure, and Pixel Package in ID Z=~3200 – Bellows/Temp. Support Z=3120 – Adjustors Z=848 – Wire Support Z=3092 – PP1 TRT Forward TRT Forward SCT Barrel Services and Beam Pipe Support Structure Services and Beam Pipe Support Structure Pixel Detector Side C Side A Beam Pipe Support Wire Beam Pipe ID Endplug Insertion Trolley PP1 Pixel Support Tube PST Support Flexures Package Insertion Riders PP1 Bellows/Temporary Support

  3. “Package” Beam Pipe Support Structure Pixel Detector Beam Pipe Support Structure Beam Pipe Service Panels PP1b Corrugated Panels installation configuration

  4. Service Quarter Panel structure carries Disk and Barrel panels as well as PP1 quarter panel on same structure This is the ‘installation configuration’ of the SQP—PP1b arrayed for insertion This configuration must be maintained in some sort of fixturing that is compatible with the ITT, to be designed Service Quarter Panel

  5. PP1b Corrugated Panels • Routing for PP1 dominates the volume at the end of the Package • Corrugated Panels proposed to support Cables at Large radius, terminate type 2 cables coming from trays inside of ID Endplate • Adjustors Align with holes in BP Support Cruciform ~100mm inside of support • Tool can grab ID of Adjustor Nut via slots—tool TBD

  6. Patch Panel One Interface to BPSS Seals PP1 Quarter Panel Trantorque PP1 Quarter Panel

  7. Survey access is poor—R Veness has proposal to survey beampipe which is acceptable Temporary support of Beam Pipe is from ‘Can’ installed on inner radius of PP1, and supported by installed quarter panels Working on re-design of PP1 Quarter Panels, will finalize design, and include detailed modelling soon PP1 Interface Continued Quarter Panel Breaks Fixation of service structure to PP1

  8. PP0 End of Frame • PP0 is not technically an interface to Beam Pipe but is a critical interface to BPSS • Tube Routing does not interfere with Beampipe Adjustors as shown on figure to right. • Note cooling tubes wrap around BPSS Barrel End Cruciform for flexibility

  9. PP0 end of BPSS • Interference between Trolley components and Services will be resolved in the final designs of Both • Details will not affect BPSS

  10. Assembly Continued—Services Added • Service Panels Are Added to top of package • Bottom of package has limited access due to ITT support structure • Note that half of PP1 is assembled at this stage, and can be fastened together—Temporary support via PP1 is possible at this stage • Installation of service panels requires a certain kinematics

  11. Panel Installation Detail • PP1 quarter plate is installed over the BPSS Adjustor • Panel is slid to lower Z up to where tubes at PP0 are just at the Barrel Cruciform • Panel is articulated out, likely by hand, to pass tubes over cruciform • Panel is slid rest of way into position • BPSS is fixed to PP1 via seals, trantorque • PP1 panels are fastened to neighbors
