Memo for Commissioning break (Mar. 2020)
- Hammering test
Task list (Done)
- Hammering test of the OMC chamber (Done 22nd Feb.)
- There is excess in the sensitivity between 100 Hz to 400 Hz
- Reported later, the main reason is the vibration to the OMC legs for the optical table inside the vacuum
- Hammering test AS table (Done 22nd Feb.)
- Reported later, the main reason is the vibration to the OMC legs for the optical table inside the vacuum
- Reflection light check (Done 22nd Feb.)
- Now we didn't use the AS PD signals for interferometer control
- There was possibility that the reflection light from AS table make dirty scattering light
- Shadowed between the OMC viewport and AS table, but we couldn't see the clear noise reduction
- Also, when we added vibration to the OMC viewport, we couldn't detect the noise increasing.
