1 LIGO-G030193-00-D Design Requirements Larry Jones Advanced LIGO, Seismic Isolation System (SEI) Structural Design & Fabrication Bidder’s Conference April 29, 2003

2 LIGO-G030193-00-D LIGO Laboratory2 Design Requirements Optical Component on HAM Table

3 LIGO-G030193-00-D LIGO Laboratory3 Design Requirements Tech Demo Unit in HAM Chamber

4 LIGO-G030193-00-D LIGO Laboratory4 Design Requirements Structure for HAM Chamber Modifications to Tech Demo design: Fit inside the HAM chamber, on support tubes Change Optical Table size, elevation, lift strength Revise pod design features: UHV sealing, locking devices, etc. Remove actuator mount dovetail features (adjustment not required) Revise flexure design: eliminate shim Revise displacement sensor design Revise mass & CG design: 5 ton limit, incl. Payload; keel likely, etc. Revise kinematic locator & lockdown designs Design to pass FEA requirements Design mass dummies & crate; write procedures for processing Review and confirm all other requirements are met

5 LIGO-G030193-00-D LIGO Laboratory5 Design Requirements Lower Section, BSC Chamber

6 LIGO-G030193-00-D LIGO Laboratory6 Design Requirements Structure for BSC Chamber Distinctions from Tech Demo design: o Optical Table is underneath; components hang from it o Stage 0 has a large clearance hole for components o Support Tube mounting structure has “stay clear” zone applied o Lift pin is included in structure o All revisions/improvements as listed under HAM Unit o Design to pass FEA requirements o Design mass dummies & crate; write procedures o Review and confirm all other requirements are met

7 LIGO-G030193-00-D LIGO Laboratory7 Design Requirements BSC Structure, Top View
