Progress report
Schedule Chart
- Type-A: 1 week delay
- Type-B: Waiting for the schedule
Type-A (Takahashi)
Past week report
[X-end]
- Checked the ACCs with the drivers.
[Y-end]
- Replaced the blades for FR in the BF.
- Pre-assemled the maraging wire for the cryo-payload with the junction box.
- Inserted the wire from the cryostat.
- Hooked the wire on the BF.
- Installed the cryo-payload into the cryostst.
- Suspended the cryo-payload from the BF.
- Tuned the BF and the F3.
- Applied the cabling between the BF and the cryo-payload.
Plan for coming weeks
- X-end: Installation of the pre-isolaotor and reassembly of the BF damper.
- Y-end: Align the cryo-payload by the FR and the picomotor in the BF.
Type B (Mark)
Past week report
- We brought the SR2 optic into the tunnel and moved it into the good mirror box. The spare mirror was moved into the not-so-good mirror box.
- Enzo assembled the SR2 rack and laid all the long cables from the rack into the cleanbooth. (Hayakawa-san can now proceed with the rebuilding of the changing cleanbooth.)
- Mark and Shoda-san took data for calibrating and diagonalizing the OL. (Due to the odd angle of the first steering mirror, the beam pattern is rotated by 62° at the QPD.)
- Enzo found nearly all in-vacuum cables.
- Enzo and Shoda-san got several more loops closed on the BS.
- Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4).
- Mark took out S-numbers for anonymous boxes in the SR2 and put yellow stickers supplied by Tomura-san on them.
- Hirata-san worked on SR procurement.
- Hirata-san worked with Mirapro to get the SRM LBB installed in the tank.
Plan for week of 12/4
- Mark at Kamioka.
- Fabian at f2f satellite meeting Mon, then Kamioka.
- Enzo at f2f then Mitaka.
- Hirata-san at Kamioka Mon-Thu, Mitaka Fri.
- Kozu-kun Thu only.
- Mirror gluing.
- IM assembly and pico test.
Plan for week of 12/11
- Mark, Fabian, Enzo, Hirata-san, Shoda-san at Kamioka.
- Kozu-kun Mon-Thu only.
- Assembly frame alignment and optical table centering.
- Move trolley system from SR3.
- OL setup.
Plan for week of 12/18
- Shoda-san vacation
- Mark, Fabian, Enzo, Kozu-kun at Kamioka Mon-Wed.

- Shoda-san 12/18-21
Type-Bp (Shoda)
Past week report
Plan for coming weeks
OMMT & OSTM (Ohishi)
Past week report
- Checked in-vac cable number.
- Possible change of mirror actuator from coil to OSEM, makes the number of cables increase than expected.
- Received quotation from FCL. Need to fix some minor problems.
Plan for coming weeks
- Resume evaluation of OSEMs.
Watchdog system (Tanaka)
Past week report
Retest in Mitaka.-->There is no problem in operation test at all.
Continuous operation test(Over 100 hours).-->
Temperature rise.-->No problem.
WD operation.-->No problem.
Start ordering mass production version.-->Ongoing(Formal request for quotation from the vendors.).
Plan for coming weeks
Plan the operation test again at KAGRA-->
- Actual test of WD operation(Retest).
- The next on site test of the WDS: From 12/12(Tue) - 14(Thu)
Other site works
Safety
- Incidents: Dropped the BF cap by 1 cm when opening it (Type-A, Y-End)
- Foreseen risks
