IM alignment
We aligned the height, tilt, and hirozontal position of IM with the same procedure as iKAGRA PR3 assembly.
We used the laser marker and standing ruler for the height and roll adjustment, and used the bubble leveler for the pitch adjustment.
Also, we measured the relative position between the IM and the EQ stop and adjust the horizontal positions.
During the adjustment, we found that it is not good to use the laser marker beam which go thorough just below IM.
We found that we have the reflected or diffractbed light when the laser hits on the edge.
Therefore, we used the light which went next to IM.
And we fixed the alignment screws for the mirror base and the RM base using plump bomb.
Checking the existing parts
We checked the parts we brought from Kashiwa and took pictures. (See an album below)
We noticed that we have 3 kinds of WB clamp thin plate. We checked the one of them seems to be for 2nd wire breaker clamp we already have in Kamioka. I will check for what they are.
Also, we looked into the SUS tool box which is brought from Kashiwa by Type-B team as gluing tools. But what we could find inside were only tools auch as allen keys.
