Subject: Aligned IPPOS, IPANG and OPLEVS 

[Yuta, Sendhil]

We aligned IPPOS, IPANG and all OPLEVs (except for ETMX and SRM).

 

1. First aligned the IPPOS by tweeking the steering mirrors inside the BS chamber.

2. Aligned the IPANG by tweeking the steering mirrors inside the BS chamber and ETMY chamber.

3. Aligned the OPLEVS for the BS and PRM was done by tweeking the steering mirrors inside the BS chamber and checked that OPLEV beams were not clipped. 

4. Centred the OPLEV beams for the ITMY and ETMY.

5. For the OPLEV of ITMX the alignment was done by tweeking the steering mirrors inside the ITMX chamber.
