| ==== Report for week of 9/10 ==== * We finish the invacuum and in air cabling for SR2, but the in-vacuum cables for Geophones and F0 Yaw stepper motor are just temporary and will be replaced later once the suspension is inside the tank. * We checked all the motors, like: *the IM picos, BF picos. * We checked the BF Stepper (Fishing rod), SF Stepper (SF Fishing rod), F0 Stepper (F0 Fishing rod). * We debugged an issue with the IP LVDTs and discovered it was a broken interface card D1402829 in the LVDT driver. We made up a working chassis with the original two driver cards, so we didn't have to reset all the phases and gains. * We reset the IP FRs to midrange. * We added a basic set of arc weights and recentered the IP. We then adjusted the verticality of the security structure. * We relocked the IP temporarily, unlocked the SF/... section and aligned the IM OSEMs. * We powered down the BS, SR3 and SR2 electronics in preparation for the power outage. === Type B (Mark) === ==== Report for week of 9/3 ==== * We did more in-vacuum and in-air cabling for SR2 and got nearly everything connected. * We debugged the IM OSEMs and fixed two broken in-vacuum cables and some mislabeled in-air cables. * We debugged an issue with the IP LVDTs and discovered it was a broken interface card D1402829 in the LVDT driver.

Report for week of 10/29
- SRM
- Hirata-san and Mark craned the LBB ring sandwich to the ceiling of the lower half of the tank, and set the heights of the jacks on the upper half.
- Fabian and Hirata-san finished the in-vacuum cabling.
- Enzo ran DC power to the second SRM stepper driver and did the rest of the in-air cabling.
- We're now ready for final tests of the SF/... items and initial tests of the PI items.
- Enzo and Fujii-kun built three geophones for SRM.
- Mark worked on the height budget.
- SR2
Enzo experimented with LISO (circuit analysis software which, among other functions, can fit measured TFs with a ZPK model) but then wrote his own fitting software in Python and used it to build Foton models of key TFs of the SR2. (These are in slots FM6-FM8 of the DAMP blocks and should not be accidentally enabled.)
