  2. Final Design Review Documentation and Drawing Overview This presentation is designed to allow one to follow the documentation path down an assembly by clicking on an item. In PDF format this will not work, but one can still navigate manually to the same place Colour coding Review documentation directly linked to file Review documentation linked to another slide Referenced documentation directly linked to file Referenced documentation linked to another slide Document change log: Pre-v1 – first draft for circulation in fibre group meeting

  3. Top-level break-down documentation T1000337 Monolithic Stage Final Design Document Design requirements docs Monolithic Assembly Docs Preparation masses Fibre pulling and welding

  4. Design requirement docs Design requirements docs T020034 Low-frequency cut-off aLIGO T010075-00 aLIGO systems design In PDR T010075-00 was referenced, document was updated to T010075-01 in Apr 2008  change impact monolithic unknown Further update in 2012 to T010075-02  no impact on monolithic T000053-04 Universal sus subsystem design requirements In PDR T000053-03 was referenced, document was updated to T000053-04 in July 2008  no changes impacting monolithic T010103-v1 aLIGO sus system conceptual design M080363 Change baseline to tapered fibres This document followed document T080091-00: Proposal baseline change from ribbons to fibres M080134 E/ITM and BS/FM pitch frequencies and d-values In PDR T010103-04 was referenced, document was updated to T010103-05 in Feb 2006  no changes impacting monolithic  has not been updated to incorporate baseline change to fibres Link now to new DCC version –v1 identical to -05 This document has been updated to take account of the note on revision d-distances by Ken Strain T0900556-v1
