| ==== Report for week of 3/5 ==== * We removed the non-vacuum-compatible ballast mass from the BS tank. * We secured all the PR2 feedthrough connections with screws. * We grabbed an extra empty rack for SRM and set it up next to the one for SR3 (we will stuff them next week). * We calibrated the SR2 SF LVDT and FR. * We put the SF cap on and lifted and weighed the SF/... section. * We moved the filter building bench and tools into the SRM area and started the rebuild of the two remaining BFs (the one from the BS Test Hang and the one with the tilted keystone). * Mark finished -v2 of the schedule ([[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=7779| L1807779]]). * Mark worked on slides for the ASJ and LVC meetings. * Sawada-san postponed the SRM mushroom work to next week and offloaded it to Mirapro. * ?? Finish recovering 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.)
