We centered the beam position of the green on the ITMX and the ETMX.
- Before that, we tuned the ETMX ADS with the GR TRANS. Actually the gain was too small. I increased the servo gain by factor of 50.
- Then with the PR3, and the ETMX ADS, we moved the POP_POM picomotors. Here, the alignment of the cavity axis and the injection beam is kept optimized. So, once we got good cavity axis with this situation by moving the pico and the ITMX, the GRX optimization guarantees the beam position on the ITM and ETM.
- We should align the green injection axis and the IR injection axis as the next step.
