We brought the OMC to the bonding lab for inspection. We found some of the EP30-2 joints between the main glass breadboard and the invar mounting brackets showed sign of delamination. Dennis, Calum, and Garilyn have been notified and are woking on the counteraction.

Attachment 1: 40% delamination. This piece is holding one side of a balance mass holding bracket.

Attachment 2: 80% delamination. This piece is holding one side of a balance mass holding bracket.

Attachment 3: 40% delamination. This piece is holding one side of a balance mass holding bracket.
