Agenda
Updates from Projects
- Birefringence simulation
The p-pol beam shape was measured in KAGRA. klog 20103
We try our best to calibrate the TWE maps. caliTWE Offset, tilt and centering can largely influence our birefringence maps. We are not sure how much error is there in Hirose-san's TWE measurements.
- We remove the gravity induced deformation in the TWE maps.
- Future plan
- Measure p-pol beam shape for ITMY.
- Measure power of s/p pol beam and arm cavity round trip loss.
- Measure p-pol beam shape vs. beam position on ITMs
