Inspection
Updated ICS (Shipment-12578) and moved those parts to Storage-9482.
Inspection showed the following:
- Serial numbers matched the packing list
- SN S1301807: We observed some discoloration on the Gore wire close to one cable termination. [Attachment 1]
- greenish tint
- appeared to be superficial
- slight removal observed when gently wiped with an IPA soaked AlphaWipe ("red wipe")
- did not follow the helical of the teflon sheath
- recommend additional inspection when Unit 4 build is resumed
- Cables were returned to the box labeled "OMC Cables" in the south cabinets in the OMC lab.
Observations for aLIGO OMC Unit 4 Build
An ICS Record Navigator search of onboard OMC cables reveals the following quantities appear to have been fabricated for aLIGO.
- D1300371 = Qty 3
- D1300372 = Qty 5
- D1300374 = Qty 3
- D1300375 = Qty 5
The leftover cables are all of the long variety (D1300372, D1300375), and the received quantities make sense. 3 aLIGO OMC assemblies used quantity 3 of each cable, leaving the remaining cables which had been stored at LHO:
- D1300372 = Qty 2
- D1300375 = Qty 2
The received cables from LHO may apparently be used interchangably, and the extra slack (~ 5", compared to the D1300371, D1300374 part numbers) should be managable.
Next Steps for aLIGO OMC Unit 4 Build
We will move forward in fabricating Unit 4 with the received cables from LHO, despite their extra length.
To complete the Unit 4 on board cable set (refer to OMC_Lab/203), we will need to crimp pins onto the PZT leads, and we need to find, clean, and bake quantity 1 4 pin mighty mouse connector.
- PZT leads terminate crimp pins inserted into Glenair Mighty Mouse 803-003-07M6-4PN-598A (per OMC_LAB/203, record navigator)
- Cable bracket interface to OMCS is Glenair Mighty Mouse 803-003-07M6-4PN-598A (per D1300376-v3).
I will ask Chub to see if there are any Class A spares of the PZT termination connector already on hand. |
