- Get pico drive screens fixed (Miyo-kun)
Final ballast mass production for BF and SF (Hirata-san).
Design of receptacles for rods with 8 mm heads.
Possible rebuild of BF
Set up build/test stand for filters.
Get filter test weights.
Find spare BF blade(s).
- Reclean stuff:
- PI (remove Kapton tape etc, etc).
- LLB damper stuff, especially Cu segments.
- Calibrate SF LVDT.
- Calibrate PI vertical LVDT.
- Set yoke on PI vertical LVDT (if necessary).
- Calibrate PI horizontal LVDTs.
- Get clean bag laundered.
- Put pointy-tipped screw in RM trolley for BS
Swap out temporary ballast mass in BF, SF.
- Return/replace borrowed parts:
- Lock washers for LBB dampers
- Temporary ballast mass (dog clamps) in BF.
Wide-mouth OSEMs from RM to Akutsu-san
Adjust height of crossbars below BF.
If possible, fix galled pole in BF level of EQ stop.
- Swap in new F0-SF maraging rod (with 8-mm heads) and new receptacles to match.
Check inside SF for lost ruler.
- Tighten PI yaw return spring.
- Get Cu O-rings for feedthroughs.
- Decide final in-vacuum and in-air cable routing (Enzo).
Calibrate all LVDTs (Enzo, Mark). BF, SF, PI-GAS, PI-H1, PI-H2, PI-H3
Remove cling wrap in BF and install vacuum-compatible heat shrink.
- Remove cling wrap on connections for PI vertical stepper and install vacuum-compatible heat shrink (needs wider diameter heat shrink or smaller pins).
- Rewire PI horizontal steppers with vacuum-compatible cable.
- Adjust yoke on BF to put top of secondary at 3.5 mm above top of baseplate (or to give ≈0 counts at nominal height).
- Adjust yoke on SF to put top of secondary at 6 mm above top of baseplate (or to give ≈0 counts at nominal height).
- Adjust yoke on PI to put top of secondary at TBD mm above top of baseplate (or to give ≈0 counts at nominal height).
Real-time and SUMCON models
- Create SUMCON models for full BS and major installation milestones.
Create controls design description (cf LIGO-T1100378).
- Make table of ADC/DAC assignments and check for consistency with D1503600 and k1visbs (Enzo, Mark)
- Understand/document/debug Kokeyama-san's DIO stuff.
- Measure LPCD and HPCD output filter response.

SR Prep Tasks
- Do rough mass budget for SR2/SR3/SRM.
- Design SR assembly frame.
- Design final SF ballast masses (Fabian).
Bread boards for SR -> すぐ見積り依頼
- Include installation work in the contract
- Total budget = 5MJPY
PEEK collet for "Small hexagon"(cable clamp) -> すぐ見積り依頼
Need simple design changes
- SUS wires(3 types) for the LBB
Change the length -> すぐ見積り依頼

- There is a mistake in the PROMEC drawing.
- Hirata-san will make a new 2D drawing
- IM wire clamps for SR
- Need to change the height
SR assembly frame -> 月曜日に見積り依頼
- Mark is checking the design from Fabian
- We should order the parts necessary to modify the BS assembly frame to the SR2 assembly frame
Need Fabian's input
Cable clamps for BF,SF and PI -> 方式を決める
