| ==== Report for week of 2/26 ==== * We routed all the cables from the BF level up via the flying saucer to the SF. * Hirata-san tried filing the SF cap to improve the fit, but without much success. * Hirata-san installed the Cu segments and cable clamps on the SF cap and the SF LVDT and FR cables. * We cabled and tested the BF cap picos and the SF LVDT and FR. (The LVDT still needs a full calibration.) * We worked on recovering the IM OSEM alignment. |

Report for week of 4/2
- Fujii-kun and Yamamoto-kun got the SR3 real time model running.
- We received the SR3.
- However Mark and Tanioka-kun found Hirose-san had applied the First Contact patterns on the wrong sides, so we took it to Yamamoto-san's lab and Toyama University and re-applied the FC properly. We also bounced a 1064 nm beam off it to verify that the HR and AR coatings were not also swapped (they were OK).
- We made magnet-standoff assemblies for both SR3 and SRM, and set up for gluing the prisms and magnets. We will attach the prisms and magnet-standoffs on Monday.
- Hirata-san did inventory of the SR3/SRM payload parts received last week and started on the inventory of screws.
- Fujii-kun, Enzo and team finished the preparation, adjustment of the SFs and BFs.
- They calibrated one SF and BF. (The remaining one SF and BF will take about another day. Also, the FR stops need to be checked.)
- Enzo and Kozu-kun finished setting up the SR3 and SRM racks. (The SRM rack still lacks a front-end, and power and network connections, but the SR3 is now ready for testing.)
- Shoda-san worked on getting quotes for the ballast masses, on design of the SRM metal mass, and on splitting the BS model to reduce the load on the front-end computer.
