[Takahashi, Miyo, Komori, Shoda]
Takahashi-san's magic again!!
We moved the suspension wire around the mirror at the HR side, and fixed the large tilt.
We have set the IM as almost horizontal using the picomotor, and fixed the mirror and the RM again.
The RM and IM were connected using the bars,.
With the mirror fixed only with the EQ stop screws underneath the mirror, we removed the RM front ring.
For security, we fixed plates on the RM so that the mirror cannot come out from the RM.
We lifted the mirror up using the EQ stop screws in order to loosen the wires.
First, we lifted the mirror in horizontal, and at some point, we lifted up the mirror only in the HR side.
After some trials, we inserted the spacer between the mirror and the RM at the bottom, and removed the 2 EQ stop screws on the HR side under the mirror.
In that situation, Takahashi-san hooked the wire and pulled to HR side from below the 2nd WB to the bottom of the mirror.
Then, we released the mirror and checked the mirror tilt is very much improved.
And we closed the RM again, and suspended IM/TM/RM.
After some tuning of the IM tilt using the picomotor, the mirror can is facing down by 3 mrad as designed.
In this situation, the IM seems to be much horizontal. (only a few mrad tilt)
With this situation, we could assembled the IRM OSEMs without touching.
Now all the OSEMs are assembled and cabled. The connection of the OSEMs seem to be OK.
Tomorrow, we will adjust the IM YAW, IRM, and IRM OSEMs.
