Gabriele | Optics | Configuration | Setup for 50mm disks |
I realigned all optical levers to measure the 50mm disks. In brief, I moved the input 2" mirrors, the in-vacuum 2" mirrors and the PZT mirrors so that the beam hits the 50mm sample and gets back into the QPD. Re-aligned everything to the horizontal reference using water. |

The four surviving University Wafers 76.2mm/0.5mm wafers have been CO2 polished. They are identified by numbers from 1 to 4 on the container. Number 4 was used for tests, so it might not be as good as the other three. During number3 polishing, the CO2 laser tripped, so I restarted the process from the beginning.

Gabriele | General | Measurements | S1600577 in test chamber, S16600573 in CR1 |
The last two set of measurements on S1600577 > S1600584 gave very low Q values, see plot. I suspect some problem with the measurement system (high pressure?).
So I installed S1600577 in the test chamber CR0.
