KAGRA Filter Cavity Meeting 2022/4/6
Date/Time: 2022/4/6 13:00 - 14:00
Connection: KAGRA Zoom2 (https://zoom.us/j/6676627462)
Agenda
- Scattering requirement for FIS (Michael)
- Parametric amplification of the OPO will increase the scattering noise coupling
- It depends on the green pump power
- The green pump power should be decided based on the trade-off between the amount of squeezing and anti-squeezing.
- This trade-off depends on the loss of the interferometer
- Parametric amplification of the OPO will increase the scattering noise coupling
How to switch FIS and FDS (HuaLi)
- Need to preserve the mode-shape after the reflection mirror
- Need to reduce the beam size on the Faraday isolators
- Clear aperture is 10mm
- Beam radius should be below 1.6mm
- Size and location of the vacuum tubes between the chambers should be taken into consideration
- We should have in-vac PZT mirrors for alignment
- Status reports
- Overall design: Matteo
- Filter Cavity: Marc
- FIS design: Yuhang
- Filter Cavity Control: Aritomi, Michael
