WHAM6--Payload, Cables & Optic Prepped For Shroud work

Nutsinee & Hugh

The Counter weights on top of the WHAM6 ISI Optical Table expected to interfer with Shroud work have been removed.  They are staged under the Support Tubes, on Stage0, and in the Spool at the Septum--Do be mindful of them and apologies for not spending more effort to get them out of the way.

The Five Cables attached to the OMC have been disconnected.  The Cables are mark with foil, 1 2 & 3 strips and 1 & 2 strips bottom to top for the 3 on the -X side and for the 2 on the +X side of the OMC.  They are coiled up, not that neatly, with the three together on the +Y side and the two together on the -Y side.  Note that one of the 3 attached on the -X side comes from the -Y side of the table, the other two attached to the -X side of the OMC come from the +Y side of the table.  The two cables attached on the +X side of the OMC come from the -Y side of the table. See first four attachments.

The M8 Mirror between the OMC and OM3 was removed, and bagged.  I scrounged a narrow dog clamp from the OM3 which was only finger tight anyway to mark the +X side of the M8 fork.  I then held M8 fork against this clamp and removed the one dog clamp holding M8 to the table and used it to mark the -Y side of the fork.  See the last two attachment for 1) before any clamps where moved and 2) after the 'marks' are in place.  Other than which side of M8 faces the OMC, I think this should serve pretty well.  I'm sure it is deterministic which side of the M8 faces M9/OMC.  There is a front and back side of the mount in which M8 is mounted.

 

Otherwise, the ISI is locked on A B & C Lockers and Robert is still making measurements.
