Abstract:

The following links are an attempt to cover all of the information for the advanced LIGO
1) Flange Layout + type
2) cable lengths
3) bracket location
4) cable count
5) flange identifier e.g. MC3 to D6 via CB6 in HAM3L
6) and related input documents

ICS/JIRA Record:

Keywords:

flange layout

Notes and Changes:

1) The HAM flange tetris (see below in related documents)

2) The BSC flange tetris (coming soon)

3) The chamber designations for aLIGO are given in the files for LHO and LLO respectively:
* D0901477-v2 file, Vacuum Chamber Designations for LHO aLIGO
* D0901490-v1 file, Vacuum Chamber Designations for LLO aLIGO

4) The designations (naming conventions) for the feedthrough ports (optical and electrical) are given in these drawings:
* D980227-x0, Naming Conventions, BSC Ports
* D980226-x0, Naming Conventions for Ports on HAM Chamber
* D980228-x0, Naming Conventions for Ports on Adapter

5) The orientation of the chambers (0 degree and support tubes for BSC chambers) is given in the following iLIGO drawings for LHO:

* D961165-v1, LIGO Vacuum Equipment Arrangement Plan, Corner Station, Washington Site
* D961169-v1, LIGO Vacuum Equipment Arrangement Plan, X-End Station, Washington Site
* D961171-v1, LIGO Vacuum Equipment Arrangement Plan, Y-End Station, Washington Site

and for iLIGO LLO in these drawings:

* D970383-v1, LIGO Vacuum Equipment Arrangement Plan, Corner Station, Louisiana Site
* D970384-v1, LIGO Vacuum Equipment Arrangement Plan, X-End Station, Louisiana Site
* D970385-v1, LIGO Vacuum Equipment Arrangement Plan, Y-End Station, Louisiana Site

In aLIGO, the BSC chambers in the corner stations and end stations of both observatories are not moved, so the orientation is the same as in iLIGO. However, at LHO the chambers from the mid-station are relocated to the end stations as H2 end test mass chambers. The orientation of these relocated BSC, H2 end chambers is the same as the corresponding BSC, H1 end chambers in the same end station.
