SEI Bellows

Document #:
LIGO-E1700397-x0
Document type:
E - Engineering documents
Abstract:
An index of documentation related to the HAM chamber and BSC chamber expansion bellows. These bellows were deployed in Initial LIGO (iLIGO) as part of the seismic isolation (SEI) system. These same bellows were used in the SEI upgrade for Enhanced LIGO (eLIGO) and Advanced LIGO (aLIGO).

Notes and Changes:
A compilation of documents regarding the expansion bellows used on the LIGO BSC and HAM chambers for the Seismic Isolation System (SEI).

Drawings:

  1. D972122, BSC Expansion Bellows Assembly (N.B.: The Senior Flexonics Drawing (in "other Files") lists the specifications for Senior Flexonics Part Number 47300.)

  2. D972611, HAM Expansion Bellows Assembly (N.B.: The Senior Flexonics Drawing (in "other Files") lists the specifications for Senior Flexonics Part Number 47288.)

  3. D980405, Shipping Container, BSC expansion bellows

  4. D980406, Shipping Container, HAM expansion bellows

Specifications:

  1. E970129, Material, Process, Handling, and Shipping Specification for Welded Diaphragm Bellows

  2. E970189, Cleaning and Packaging Specification for Hytec Stainless Steel Bellows Assemblies and Components

  3. C982977, Packaging of Bellows (a note about the need to restrain the bellows in their custom packaging during transport; essentially an addendum to E970189)

  4. C0900859, Statement of Work for the HAM Bellows (Some additional HAM Bellows were procured for Advanced LIGO. The RFQ and SOW for both HAM and BSC Bellows for Initial LIGO are in paper form somewhere.)
