Print this reportAfter the initial alignment, we performed the several trial of DRMI ADS.
- Engaged IMMT2 and PRM ADS As expected, it was stable
- Engaged IMMT2, PRM and SRM ADS We tried to engage the IMMT2, PRM and SRM ADS. Before the SRM became stable, lock loss happened. From the error signal of SRM ADS, the value close to zero, but lock loss happened. t - Engaged IMMT2, PRM and BS ADS Similar with the above situation, BS ADS cannot be stable state, POP 90I increased, but lock loss happened.
- Engaged IMMT2, PRM, BS and SRM ADS
In the situation of this morning, we cannot reach the stable alignment for those ADS, but the direction of the ADS would be fine.
- Engaged IMMT2, PRM, BS, SRM ADS and SRM BPC by SR2 We tired to engage those controls with several gain tweaking, but we failed the stable lock.
