We have glued the dumbbells to the magnets that will be used for the ITMs
We made two sets of glued pair of the dumbbell and the magnet ( one set means 6 pairs of the dumbbell and the magnet. Therefore in total we got 12 pairs. )
You can see the detailed procedure we did on the LIGO document E990196.
Actually we performed one different thing from the documented procedure;
we made scratch lines on the surface of the both dumbbells and magnets by a razor blade.
According to Steve and Bod, these scratch make the strength of the glues stronger.
Now the dumbbell-magnet pairs are on the flow bench in the clean room, and supported by a fixture Betsy sent us.

On the bench the left set is composed by magnets of 244 +/- 3 Gauss and the right set is 255 +/- 3 Gauss.
