Abstract:

I implemented BPC of ETMY and ETMX.
Then, I tested BPC + ADS with PRFPMI configuration.
Though I tested only pitch DoFs, both BPC and ADS seems working well.

Detail:

Since BPC pathes was implemented into Type-A payload models, I tested the BPCs.
This time, I implemented centering loop on ETMs (exciting ETMs and feedback to ITMs).
Configuration is PRFPMI_RF_LOCKED and setting of the BPCs can be seen in fig1.

After implementing BPC, I tested pitch BPC with pitch ADSs in PRFPMI configuration.
Figure 2 shows the time series of IR transmission power and pitch motion of the mirrors.
All four mirror dirft seems to be stopped and no significant drop of transmitted light can be observed.
So, both ADS and BPC seems working well while only ADS didn't work in the previous time (klog23933).
