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 and compare the beam shape simulation with the measurement. 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
