Document type:

E - Engineering documents

Abstract:

aLIGO SUS BSFM Acceptance Documentation
This document will be the overarching acceptance document for BSFM, giving details on documentation etc common to all beamplitters and indicating links to individual suspension documentation.
The notes and changes section of this filecard list the headings from Acceptance Review template E1300457-v3, with appropriate links.
Note that we are no longer using folding mirrors (FM). However most of the documentation till refers to BSFM.

PUNCH LIST - Operation Manual (Mark / Norna), BS Top Level drawing (Janeen / Eddie), Organization of storage (Ops task).

SIGNED - Calum Torrie signature on 24th March 2014 closes this BSFM General Acceptance Doc on behalf of chair and committee .

Punchlist items and their resolution will be tracked in T1400181. They will not be updated on this Acceptance Document filecard.

Notes and Changes:

v2: removed reference to AOSEMs in document ( there are no AOSEMs in BSFM suspensions). v3: some minor edits. Also addition of links in section 8 on how to access software. v4: added more info on test results in section 7.1 v5 minor edits v5: 3rd Feb 2014 - notes added by CiT with view to take this through to completion. v6: updated the general document to include link to useful electronics wiki in section 2c. v7: updated section 8 with more info on SVN (written by Stuart) v8: added link to ops manual for testing procedures in section 7. v9: added electronics requirements link to document (Norna 17 May 2014)

to access can be found in Section 8 of the above main 
document.

3. Materials and fabrication specification

MANUFACTURING CANTILEVER SPRING BLADES FOR AdvLIGO .
 REVIEWED. CLOSED 

4. Parts and in-process spares inventoried
Assemblies are recorded in ICS. Individual spare mechanical parts which
 have gone through clean and bake are in general recorded in ICS. 
In some cases spare sub-assemblies have been put together but not yet recorded as such. 
Electronics are recorded using the S-number scheme. 
A separate document has been prepared which summarises storing of spare parts, see T1300908.
 NOT PROJECT JOB TO DO. ORGANIZE SPARES IS OPS. THIS SHOULD BE ADDED TO PUNCH LIST TO REMIND TO ASK AGAIN. 
CLOSED  


5. Assembly procedures
https://dcc.ligo.org/LIGO-E1000686 BS Assembly and Alignment Procedure
https://dcc.ligo.org/LIGO-E1000753 Preparation of a 
beamsplitter or folding mirror (BS/FM) (Gluing primary and 
secondary wire break-off prisms) 

https://dcc.ligo.org/LIGO-T1200105 Review of Design and Procedure for Use of BS/FM Prism Jig 

This document appears to just be a collection of 
comments to the documentation under review, with little to 
no resolution. The conclusion states that the resolution of
 these items were tracked over SUS telecons, and that 'As 
of 2nd October 2012 [to the best Mark Barton's knowledge] 
everything that needed doing was done.' I went back to the 
notes for Sept 2012, 
and I find no reference to this material.
Spot checking the action items from Section 3,

(1) None of the DCC numbers cited in Dennis' response 
table, which are actioned to be captured, exist in E1000753.
(7) There is no mention of the word 'flipper' in 
E1000753, and a novice's quick glance over the procedure 
doesn't seem to mention anything that might be a procedure 
for something being 'flipped.'
(12) Is Janeen satisfied with the diagrams that are 
presumably now included?


Based on the spot check and SUS telecon notes, finding 
a record of the resolution of all the mentioned action 
items is difficult at best.

 Note added by Norna. The above comments have been addressed in v3 of T1200105

6. Installation procedures
https://dcc.ligo.org/LIGO-T1100489-v2 BS/FM installation 
lock-down procedure
Chamber installation procedures are particular to each 
suspension.

7. Test documents
Suspension testing: https://dcc.ligo.org/LIGO-G1200070 
Ideal Order/Contents of aLIGO Triple SUS Testing / Commissioning

Testing related documentation is kept on the SVN 
repository, as are transfer functions, spectra and B&K 
results. Further details are given in the main document 
above, including DCC links to other test results such as 
OSEMs, blades, vibration absorbers etc.

Electronics testing: The results of reports are posted 
under the serial number of the chassis. Further details are 
given in the above main document.

(added by Norna 24 March 2014) A useful link for key testing procedures 
is the Checkout/Testing page in the Operation Manual at 
https://awiki.ligo-wa.caltech.edu/aLIGO/Suspensions/OpsManual/Testing

     - the gui interface for the userapps svn: 
https://redoubt.ligo-wa.caltech.edu/websvn/listing.php?repname=cds_user_apps
     - or the simple html interface  to userapps svn:

Review Comments from Fabrice:
I reviewed the MEDM screens using H1 BS. 
Everything is working well. 
(except guardian and some details in ODC screens, but this 
is not SUS responsibility). 
All the models and screens are well under revision control 
and up to date. (updated the last time on 10/29/2013)

 Section 8 of document has been updated to include more info on SVN
 REVIEWED. CLOSED 

9. Operation Manual
https://dcc.ligo.org/LIGO-E1200633 aLIGO SUS Operation Manual
This covers quads and triple suspensions due to large 
element of commonality
Comments from Jeff Lewis:  Significant work has been done 
on the SUS Operations wiki page, however the Operation 
Instruction section is yet to be completed as of 
10/30/2013.  This could be added to a punch list.
 REVIEWED. PUNCH LIST ITEM. SEE ABOVE. 

10. Safety
