Past week report
[X-front]
- Lifted up the EQ stop to access the F3 and recovered the touching problem in the F3.
- Lifted down the EQ stop again. Extended the EQ stop to the F1 stage.
- Tuned the F1. The lowest frequency was 0.45Hz. When the filter was suspended with the cap, it went to the bi-stable.
- Decompressed the blades. Finally the frequency was around 0.5Hz.
- Checked the FR in the F1. Adjustable rage of keystone was +/- 4mm.
- Cabled around the F1 and checked the cable connection.
- Lifted down the EQ stop. The end plate for the F1 was sit on the frame lock.
- Extended the EQ stop to the top ring.
[X-end]
- Adjusted the height of filters.
- Connected the PT100 sensor to the monitor line for CRY.
- Check the FR range in the BF.
Plan for coming weeks
[X-front]
- Set the bridge frame.
- Prepare for the pre-isolator.
Type B (Mark)
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.
Plan for week of 4/9

Past week report
- I found that the most of the magnet direction of PRM IM flag are facing wrong. We should fix the consistency with the compensation magnets at some point.
