I feel like to align the IMMT1 so that the POP90 gets maximum. I tried it, and the POP90 get increased about 20 %. I haven't completed it yet, due to the earthquake, so if someone can help it, please do it after the recovery from the earthquake.
The attached file shows the IMMT1 oplev (upper two) and POP90(mid-lower). At around t = -1000, we centered the IMMT1 oplev centered.
Also, I included the BPC signal (bottom) of PRM in the figure to show that the BPC signal also moved with the IMMT1. So, the PRM BPC is working well, and posssibly it can be used for the IMMT1 ASC.
The alignment procedure is as follows:
- Lock PRMI
- Engage PR3 and IMMT2 ADS
- Move IMMT1 with inough ramptime.
I wanna note that the IMMTs coils has small range, so I did used the pico to offload the ADS signal.
