Summary Report

Type-A

IY: Recovered the F1, F2 FRs. Compressed the F0 blades more to extend the height range. Total adjustable range became +/- 10.6mm.
IX: Calibrated the BF damper. The LVDT driver was replaced to the low noise one.
The corrugate tube fixing jigs were replaced in IY, EY, and EX.

Type-B

This week we installed SR2 oplev hardware and routed the power cable from the rack to the SLED. Next week we'll align the optical components.
On the week before the ast one, we installed the SRM oplev optics, aligned the optical components and calibrated the QPD in terms of their displacements.
[Terrence] SRM optical lever was calibrated and diagonalized. But the noise floor is too high to render it useful for my purpose. klog 17499.
I synthesized a sensor correction filter according to the seismometer noise and seismic noise in KAGRA. It resembles the LIGO filter but with lower noise amplification. (show notebook)
About SRM.
- I was given a month to work on the SRM and unfortunately I can't finish everything that I wish to do. Today is the deadline so I will stop working on it, unless I am given more time to work on it.
- It would be useless if I don't share my knowledge with commissioners. But I know you are all busy and you might already have your own plan on how to configure the suspensions. I don't want to force people to listen to my stuff. But, just in case if people want to know how I do particular things, I will be very happy to share.

BS Outer frame

The brace (support beam) for BS outer frame was not attached in O3. The brace itself is ready.
We have a structure analysis for the frame prototype (SR type), but not for the BS type.
I like to ask Sato-san the analysis for BS type to confirm the availability.
