Continued work of klog22611.

Abstract:
I prepared the breadboard on the pylon for OMMT2 trans monitors.
Also, I replaced the mirror inside the chamber to new one.

Detail:
We checked several stuffs to construct OMMT2 trans monitors.
1. Breadboard on the pylon: stored inside the clean booth.
2. Adapter for breadboard and pylon: stored at the PSL-side rack between MCF and MCE.
3. QPD legs: all are for 4 inch height, which might not be sutable for the OMMT2 trans monitors.
4. BS, lens, and mirrors: not yet found.
Since we need QPD legs, I asked Akutsu-san to take a quotation.

After checking the stuffs, I installed breadboard on pylon (fig1).
Then, I replaced the mirror inside the chamber to new one (JGW-D2113030-v4, TFMQSP-50.8C11-W0.5D-1064sp-ARS-30/50D).
Old mirror (I'm not sure the detail but maybe thorlab mirror) is stored at the decicator near OMC rack (fig2).
Wedge direction is shown in fig3.

After installing new mirror, I checked the beam from viewport and it passes through almost the center of the flange (fig4).
