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. [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=17499|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. === Type-Bp === === Type-C === === Electronics === * Power supply for IX and IY was changed. === Control === == Schedule == See [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/Schedule|Schedule]] * Type-A team: Finalization of IX and EX. * Type-B team: Oplev alignment in SR2 and SRM.

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. == Travel Plans == The week from 7/19 * Takahashi: 7/19-21 * Sato: 7/19-21 * Hirata: 7/19-21 * Yano: 7/19-21 The week from 7/26 * Takahashi: 7/26-30 * Hirata: 7/26-30 * Yano: 7/26-30 == Next meeting == * 2021/7/30(FRI)
