KAGRA VIS (Mirror Assemble)
AyakaShoda - 11:35, Friday 18 September 2015 (179)
IM (almost) assembled

Fujii, Hirata, Shoda

We assembled the IM for PR3 except for the wire clamps and the OSEM flags.
Please see the pictures.

The reason why we did not attach the wire clamps is the pins do not fit well. We can fix it by pushing, but if we do that, it seems difficult to remove the clamp base.
The clamp bases and clamps are paired so that the pins for alignment fit well.
But the side board, where the clamp base is attached, is not paired while the clamp base also has alignment pins.

Also, the picomotor length did not fit to the cad drawing.
I could not find why since we do not have cad file it self at that time.
We just adjust the length of the picomotor so that the the position of the moving mass is almost at the center (by eyes).

Note: one of the picomotor driver did not work well. It goes on forward, but not on backward.
