[Jeff Koji]
- Placed the optics on the PD/QPD path
- Checked the alignment of the beam on the dummy PD/QPD mounts
- There is a bit of (~0.5mm) shift of the spot position from the center. Mainly downward. This is well within a ball park of the PD mounts.
- The PD/QPD path gluing will take place tomorrow.
- Went to the 40m and received the DCPDs from Bob's lab.
- Took six ISC QPDs for the sake of the OMCs.
- They are now in the OMC lab.
- Measured the B mirror / E mirror R&Ts.
- Found anomalously high loss (3%) for the B mirrors (BSs)
- Went through the all mirrors. Some mirrors (3 or 4) seemed less lossy (<~1%). They will be used for the DCPD BS. |
