Summary
Following the previous entry the South path construction was at the point where mode matching was needed for the South Cavity.
We also needed to install a resonant photodiode for the PDH lock and start to prepare the optic in transmission.
Coonclusions
- The light is resonating into the South Cavity with a visibility = (Vmax-Vmin)/Vmax = ~ 0.75.
- We also have the resonant PD for the light reflected from the cavity.
- Camera and ISS PD in transmission of the South cavity have been aligned too.
- All the cabeling are hooked, but they need to be tidied up.
Note:
- Lenses have been adjusted and slightly changed compared to the previous entry.
- The alignment of the cavity took me a while. The mounts for the steering mirrors on the
periscope are very sensitive, here the alignment requires a bit of more attention.
- All power supply and cables are connected. I just need to verify the HV power supply settings.
