Type B (Mark)
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.)
