3 Final Design Review Documentation and Drawing Overview 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 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

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

5 Design requirements docs T Universal sus subsystem design requirements T v1 aLIGO sus system conceptual design T aLIGO systems design T Low-frequency cut-off aLIGO In PDR T was referenced, document was updated to T in Apr 2008  change impact monolithic unknown Further update in 2012 to T  no impact on monolithic In PDR T was referenced, document was updated to T in July 2008  no changes impacting monolithic In PDR T was referenced, document was updated to T 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 Design requirement docs M Change baseline to tapered fibres M E/ITM and BS/FM pitch frequencies and d-values This document has been updated to take account of the note on revision d- distances by Ken Strain T v1 T v1 This document followed document T :T : Proposal baseline change from ribbons to fibres

6 Preparation masses Preparation masses Drawings and parts of monolithic assembly Mass preparation procedure documentation Tooling for bonding

7 Fibre pulling and welding T CO2 Silica Fiber Pulling Machine description E Hazard Analysis for Fiber Pulling & Welding E Monolithic stage fabrication and assembly procedure Fibre production and preparation Welding Fibre pulling and welding T050213T ETM/ITM Monolithic Stage Fabrication and Assembly

8 Mass preparation procedure documentation E ETM/ITM mass preparation procedure E ETM/ITM PUM preparation procedure Mass preparation procedure documentation NOTE: 1. Procedures have been tested extensively at LASTI for the prototype quadruple suspension. Document T describes bonding of the ears onto the ITM and PUM at LASTI and gives insight in the bonding of the prisms using VacSeal adhesive. The bonding of the magnet flag assemblies at LASTI is described in T080245T T E Generic bonding procedure E First Contact procedure E Jig settings calculation spread sheet
