RM hanged, Top filter set

[Takahashi, Okutomi, Fujii, Shoda]

We aligned the RM and the clamped the wires. The winch is removed from the top of the IM.
Also, we installed the EQ stop systems both below and above the IM.
The top plate and the traverser are sitting on the assembly frame and the EQ stop poles are connected to the interface plate.

During the RM alignment, we align the RM using the winch according to the OSEM and the flags.
However, some of the flags do not come to the center of the OSEM. In that case, loosen the OSEM and set then according to the OSEM flags.
Now, none of the flags does not seem touching.

The EQ stop are attached properly using the BUMAX screws. And the EQ stop poles above the IM are replaced to the correct ones.

We used the eye-nut turn buckles to lift the top plate unit horizontally.
Then we could connect the interface plate and the EQ stop poles without galling screws.
Now, the EQ stop plate below the IM is suspended from the interface plate. (Nothing is sitting on the hanging frame.)

 

Tomorrow's plan:
Signal check using the digital system. (We already checked the coil resistance and the diode voltage.)
Hang the IM from the bottom filter.

Also, we put the spare mirror back to the mirror box so that we can send the spare mirror back to Kashiwa.
